Show HN: Return Ledger free portfolio TWR/XIRR tracker with AI PDF import
unrated
Hi HN, I made a simple single-page tool that computes portfolios return / performance (TWR and XIRR), gross and net of fees and tax. It requires logging all transactions. It's client-side, with no accounts, and data lives in the browser localStorage. It started as a personal tool . I wanted a way to understand what was the return of my portfolio and of a tenanted rental property (XIRR). The experimental part is an import: you upload a broker's trade notice PDF and an LLM proposes one ledger row, which you confirm. It solves a problem I had: understanding my bank's documents, especially for bonds, at least here in Italy, where there are multiple numbers to add or subtract to get the real return. It's an alpha. I've only tested it on real documents from one Italian bank (about 40 notices, all correct on the first attempt) and on a few synthetic ones from other countries, so I'd really like to hear how it does on yours. Caveats: the PDF goes to the model provider and is neither stored nor logged by me. The AI import needs an access code, because I'm paying for the API calls out of pocket, so ask me by writing to [email protected] and I'll send one. The tracker itself works without it. I'm looking for some feedback regarding AI interpreting other brokers' documents (no need look at sensitive information, though). I'm happy to answer questions about the validation approach or the architecture (Azure Static Web Apps with a small Python function behind it).

Show HN: Koody for Business – AI bookkeeping for people who aren't accountants
unrated
Hi HN, I'm Hallie, founder of Koody. Today, I'm launching Koody for Business: AI-powered accounting, bookkeeping, and tax prep software for sole proprietors and small businesses. For years, I used accounting software for my business. I went into it to create invoices, categorize and reconcile transactions, and work with my accountant to prepare our books. I often dreaded having to do it. There were so many transactions to get through in a handful of different currencies, and I found the whole process draining. The software I used (and refuse to name) worked really well. It was capable accounting software, and I'm not trying to suggest otherwise. But for me, accounting had become a bit like going to the dentist. You know it's necessary and useful, but that doesn't stop you from feeling anxious about it or wishing you didn't have to go. What makes this personal is that I've always been good at accounting. Throughout secondary school, I was the best student in every financial accounting class. I was also the class prefect, so I would regularly collect everyone's homework and take it to the staff room for submission. My accounting teacher used to ask me to put mine on top because she used it as a marking guide. I then went on to study finance in undergrad and eventually earned an MBA. So accounting isn't an unfamiliar subject to me, yet dealing with my own books made me extremely sad and anxious. I'm building Koody for Business because I want business owners to see accounting through my original lens: something simple and enjoyable that doesn't require a degree to understand. Koody automatically categorizes business income and expenses and uses those transactions to produce cash flow insights, profit and loss reports, and records for Schedule C and tax prep. There are two workspaces: personal and business. The business workspace lets you manage your business finances separately from your personal finances, even when you use the same bank account for both, as many sole proprietors do. You can keep each transaction in the appropriate workspace, so personal spending stays out of your business reports. You can use Koody just for your business, just for your personal finances, or for both. Give Koody for Business a try at koody.com/business. I'd love to hear what you think.

Show HN: Treesum – Replace MS Excel/Project with a Code Editor
unrated
# Intro The goal of this software is to make it easy to get the plan that's in your head onto the page. Start with the outline then add details. Then more details. Then numbers: costs, time, quantities. Then organize and categorize with #tags. All the sums, graphs and pivot table functionality happens automatically in the Calcs, Timeline, Stats views. And everything looks nice without you having to format it. Currently, it's all local, saved in your browser. Save your plan permanently by downloading the '.tsum' file. Open (upload) the '.tsum' to start working again. Everything happens in the browser. The files are stored where ever you like. The '.tsum' file is just text - human and AI readable. Use it to plan anything. We hope it works like your brain does - by organizing things in trees. # Story This software is entirely vibe-coded. It had to be - none of my developer friends would help me out. The front end JS on this app is too complex for a part time developer like myself. I've had this idea for a while and was only able to bring it to life because of AI. It may not gain traction, but at least I can put it out there, use it myself, or stop thinking about it altogether. It's amazing to see it and actually use it - to know if my idea was good or not, at least for me. And I'm actually happy with it and have been using it. If you have thoughts about the idea, feel free to let me know. I'm open to suggestions for improvement. # Disclaimer This tool is mainly intended to help with project planning. But it can be used for any data that looks more like a tree than a table. Creating a quote or estimate for one-off projects is my favorite use case. The varying structure of costs across lumber, electrical, concrete and labor fits well. Obviously, it doesn't replace all the many things Excel can do. It tries to improve on MS Project by making it easier to get your schedule on the page by coding into an editor instead of poking at menus in a GUI. It is still a proof of concept at this point, not a bullet-proof software package. If there's interest, it will be developed further. For now, it's good enough for me. # Roadmap I want this software to be the Excalidraw of Excel: free, simple, browser-based and fun to use. There are great things that Excalidraw does that would require servers and more costs. These features could be turned into a paid product if there is interest. So, if you're interested, please let me know: treesum.app (at) gmail.com. # Thanks HN This project would not have been possible with out AI. But also not without HN. Reading HN nearly every work day really shapes how to think about software and presenting it to people - especially for someone who is not a full-time developer. It's a great community and I've happily been a member since (at least) 2013.

Show HN: Visi – Excel as a CLI
unrated
This project doesn't solve a burning problem for me, but it's more of a curiosity-driven experiment asking one question: with LLMs and fuzzing, how close can I get to a 100% Excel-compatible spreadsheet engine? After working on this for a couple of months, it seems to be pretty close now (and in some cases, more accurate than Excel). Recent fuzzing runs have been unable to find discrepancies with Excel, but I think that there is still a long tail of cases out there. Nonetheless, visi has worked well so far for casual agentic use cases, e.g. modeling the minimum spend to break even on a credit card annual fee/running a DCF model for a company. To view the resulting workbook, I've been using this OOXML viewer (HN link): https://news.ycombinator.com/item?id=48436863 Note: the name "visi" is a nod to VisiCalc. It is also easy to type.

Show HN: An App that names each cell in a spreadsheet
unrated
Upload an excel spreadsheet. A pipeline labels each cell using the name the author already gave it. It makes it easier to understand and my thesis is that it will also help AI models reason faster and better. I have spent 20 years and 10,000 hours building and reviewing spreadsheets, in consulting and investing. The Trace tool would have made me catch the time I accidentally summed a date cell into a revenue total and would have saved me 1,000 hours of A1 hell. Labeling is currently a heuristic pipeline that detects common label patterns (year strips, text strips next to data, etc) and then a "walker" walks each cell till it finds its label. After this stage, remaining issues are sent to an AI (this takes a while on large sheets). Note -- still many edge cases but it works decently for well constructed spreadsheets - e.g. it still gets confused when authors put a label to the right of data cells, with sparse tables mixing text data and numerical data and with text and date formulas serving as labels, etc. Ts/Py stack. To see a cell's labels, upload a file, click on any cell and click the trace button. Pls give it a try.

Show HN: VNetMap – A zero-knowledge E2E encrypted network topology mapper
unrated
For years I have used Excel to document my Home Network. If you have switches, servers and many sevices i know you know what i mean by that. There was also no good way to know which patch panel cable runs to witch outlet and what's connected to it. So I started building my own Angular app to map my network. I quickly wanted to automate the process of discovering new devices so i don't have to add every device manually. So I built a Docker agent that runs nmap to scan the Network. With the Scanning agent I also got the benefit of tracking all the devices and its state. After some development and testing, I wanted to share my app with others. The most important thing for me was then to implement E2E Encryption because nobody wants to have their whole network in a cloud readable by anyone. All data gets encrypted locally on your device and then gets transmitted to the backend. A big problem was and still is, the whole nmap discovery. Different vendors use different methods to broadcast the hostname (mDNS, NetBIOS, pure DNS). Now, four months later, I finally have a production version. Feel free to test my app and i would like to get your opinions and feedback. Live App: https://app.vnetmap.com GitHub (Docs & Agent Setup): https://github.com/vNetMap/vnetmap-issues

Show HN: Sommelier, an Excel Addin for your agent
unrated
Sommelier (there is a nice wordplay on Excel and pairing) is an Excel Addin + relay server that lets your agent work hand in hand with you while you're working on an Excel spreadsheet. It's heavily inspired by the excellent marimo pair. It's useful when you either don't want to use Microsoft Copilot, want to use a local model + harness for security reason, or want to use an agent that already has access to personal data. I've tested it with some harnesses (pi, opencode, codex) but I guess that it should work on many others. Not having a Microsoft developer account, I've yet to publish it to the marketplace, but it's sideloadable. While the first prototype was written by me, I've only kept the core and let an LLM rewrite the code.

The motive was to code a programme inspired by VisiCalc and Lotus 1-2-3 interface, running on terminal, but fully compatible with the current universal standard of OpenXML (xlsx files for spreadsheets). Coded in Go lang; apart from my being more familiar with this programming language, it helps making a single executable, low on resources. Also, I like Go's compiler ability to cross compile to many platforms and OSes (which I personally often meet through my daily job). By the way, tuisheet is much more thoroughly tested and used on Linux than on Windows (or Solaris, AIX, BSD).

Show HN: Windows-style Excel ribbon shortcuts and formatting macros for Mac
unrated
I worked in finance for 5+ years and became extremely proficient with Excel on Windows. When I left to build a start-up, I switched to a Mac, and was frustrated by the absence of the shortcuts I had become accustomed to, which is why I built LightningXL on the side. LightningXL is a menu-bar app that uses macOS Accessibility tools to add back two things on Mac that I had on Windows: (1) Access to all the ribbon commands across Excel/PowerPoint/Word using the same shortcuts as on Windows, and (2) formatting / auditing / tracing macro capabilities, similar to Macabacus. None of the existing options provides the same scope of functionality: Accelerator Keys helps with the ribbon shortcuts, but not the macros, and the key tips that Microsoft released in the past year or so don't let you traverse the full ribbon. My Excel efficiency is now close to what it used to be on Windows, so I wanted to share LightningXL more broadly for the other power users out there who for a multitude of reasons are using Macs. Would love feedback on what improvements can be made and what other functionality to add for Excel or the rest of the Office suite.

Show HN: Pull every comment out of a Google Sheet, in the browser
unrated
I spend a lot of time working in Google sheets. Often, I will collaborate with up to 50 other people in the same workbook. One specific org I worked at had a strong preference for using comment threads in Sheets extensively to ask questions, give feedback, and raise risks. Sheets would regularly get 70+ comment threads across multiple tabs with dozens of contributing teams. As the owner of the sheet, I wanted a way to document the comments to retain traceability on all of the various conversations. To my surprise, there was no function built into sheets to scrape, count, sort or manage comments at all. I also couldnt find any good third party add-ons to solve the problem. So I built one myself. I discovered that the Drive API gives you the comment text, author and state, but doesnt give the location of the comment which was crucial. Thankfully, the .xlsx export has xl/threadedComments with the cell reference, timestamp, author, resolved flag and parent ID. How it runs: JSZip in the browser, no sign-in, nothing uploaded anywhere. I am in the process of having the app verified to be hosted on Google Workspace Marketplace, but in the mean time the tool is available at: https://github.com/bsunter93/commentpulse

Show HN: Add legally binding signature to your Google Form
unrated
While launching products, I needed a lead form on our website. Google Forms had everything I wanted: easy setup, Google Sheets integration. But embedded on our site it looked like a patchwork. So I restyled it with CSS to match our branding. I launched that CSS hack as an addon and thousands of customers started using it. One customer segment, doctors, liked our addon but were worried about HIPAA. So we studied HIPAA regulations and built a HIPAA compliance product with e-signatures, PHI field masking and intake forms. But, only the signature feature took off. So, we renamed it as Formesign and pulled the other features back in around it and made it into a DocuSign alternative that lives inside Google Forms, syncs responses to Google Sheets and saves the signed PDF in Google Drive. Would love your feedback and learn more about your Google Forms and signature usecases.

Show HN: JavaScript grid and pivot library built for coding agents
unrated
Hi, I am building a js library for grids (and pivot tables) so that coding agents can use our primitives to deliver a grid based on your specifications. I started working on this problem because data displays like grids / pivot tables are tricky to get right as more and more features pile up (features like: pagination of data, virtualization, pivots, grouped views, custom renderers, filters, sort, etc) Pre llm and coding agents, I built https://github.com/chartshq/muze (that later got acquired by mode analytics) with grammar of graphics for developers. But I have always felt a library built for agents would have a fundamentally different philosophy than the one built for devs. What does an agent first js grid library mean? The library comes up with few primitives and mental models that agents can use reliably ( https://www.superplot.dev/grid/our-approach/#principles/tabl...) alongside the design and architecture of the grid (open closed system + data flow + relinquishing right control to agents). Thus enforcing enough abstraction for agents that produce fewer bugs in a single shot ( https://www.superplot.dev/grid/our-approach/#principles/head...). How is it different from a lib built for devs? Unlike a lib built for devs where the abstaction layer is much closer to humans (config driven like highcharts / aggrid), I belive having a different layer of abstraction from carefully defined building blocks and stable contracts help agents build reliable and stable outputs. For majority of the usecases, a user can ask an agent to build a particular representation of the grid (without waiting for the library to support it internally) to their liking. The agent would then go and build the grid with given constructs acting as guardrails. (Ofcourse there is a limit to that, for example if you want to do something which is outside the scope of mental model) What does it support? - Headless grid with virtualization - Local in browser datasource via duckdbwasm (supports pivot / tree / grouped data ops) - External datasource connection via our IR (codegen to db / semantic model should be easy given llm like structures) - Pivot + tree view + grouped data view - Table algebra support (that gets translated to IR for external datasource, for which agent can do codegen) - Pagination / data evictions for billions of row handling - Metadata plumbing (for usecases like complex cells where data needs to be generated from multiple differnet parameters) - Usage patterns / documentations (we are working on this) Some demos: https://www.superplot.dev/grid/#demos Github: https://github.com/superplothq/grid Would love to get your feedback on the approach as I continue to build the library.

Show HN: Browser only CSV editor, data never leaves your machine
unrated
The current software I am working upon as part of my full time job, I have to deal with very long JSONs and lot of CSVs. For editing or viewing JSONs my first and obivous choice was jsonher.io, it’s the most wonderful JSON viewer I have ever seen. But I wish I could the same for CSVs too, when I googled it, I couldn’t find anything good. Most of the tools were asking me to sign up, some of them allowed me to open CSV but then came a big popup asking for my credit card so that I can edit it or use some filters, and lot of them were sending CSV to server in case it was large. I will be honest, there were some which were no signup or no server, but their UX was bad - sublime was showing the content better than those. Then I started building one for myself, and it turns out building no signup, browser only CSV tool is actually possible even for managing large CSVs; I was able to make it up and running within days and it turns out to be awesome - apologies for shameless bragging. Later I added support for downloading content in JSON and other alternatives of CSV like PSV, TSV, SSV, etc. It has all the basic functionalities for working with CSVs - filtering, sorting, editing, deleting, downloading in your desired format. In near future, I am planning to make it one shot CSV editor for all kinds of platform - browser extensions, desktop app and hopefully mobile apps too ( I am bad at building mobile apps, but I will try my best ). Do check it out and let me know in comments, what you feel about it.

My team used PopSQL and SeekWell to get data from our DBs into Google Sheets on a schedule while also sharing a library of company specific SQL queries. Both were shutting down, so I built a replacement covering just the parts we actually used: connect a database, write and share SQL, schedule the results to Sheets or Slack. Yes, a cron job running a python script does the same thing for free. But getting non-technical teammates to use that is the hard part, and that's really what this solves. Another thing I strongly believe is that data belongs to everyone in the company. People will figure out use cases when they have access to the data, and people are way more productive when the access is not gatekeeped. It's narrow on purpose, and I'm happy to build almost anything people need in a tool like this. What would you want to see?
