  • Project mention: how to work with .xlsx files? | /r/node | 2023-06-28

    ExcelJS and XLSX (SheetJS) are great libraries to work with XLSX files. The former I've found a bit easier to work with but less efficient in general.

  • Parsr

    Transforms PDF, Documents and Images into Enriched Structured Data

  • Project mention: LlamaCloud and LlamaParse | news.ycombinator.com | 2024-02-20

    I'm part of the team that build LlamaParse. It's net improvement compare to other PDF->Structured Text extractors (I build several in the past, includig https://github.com/axa-group/Parsr).

    For character extraction, LlamaParse use a mixture of OCR / character extraction from the PDF (it's the only parser I'm aware of that address some of the buggy PDF font issues, check the 'text' mode to see raw document before reconstruction), use a mixture of heuristic and Machine learning models to reconstruct the document.

    Once plug with a Recursive retrieval strategy, allow you to get Sota result on question answering over complexe text (see notebook: https://github.com/run-llama/llama_parse/blob/main/examples/...).

  • Project mention: Building a flat-file CMS with Angular | dev.to | 2024-03-05

  • Project mention: Show HN: Matrices – explore, visualize, and share large datasets | news.ycombinator.com | 2023-12-07

    Hey HN, I'm excited to share a new side project I've been working on.

    The product is called Matrices. You can check it out here: https://matrices.com/.

    With Matrices, you can *explore*, *visualize*, and *share* large (100k rows) datasets–all without code. Filter data down to just what you want, visualize it with built-in charts, and share your results with one click.

    You can use it today (no login or waitlist or anything). Just copy and paste your data from a google sheet or CSV file.

    It's hard to describe the feeling of "gliding over data" you get with Matrices, so I'd rather *show* you how it works instead. This 75s video will give you a sense of how it works: https://www.youtube.com/watch?v=Rrh9_I3Ux8E.

    Data is stored locally in your browser until you publish it, though small sample does go to the OpenAI APIs for AI-assisted features.

    I started building Matrices because I wanted a tool that made it easy to explore new datasets. When I'm first trying to dig into data, I'll have one question... that leads to another... that will invariably lead to five more questions. It's sort of a fractal process, and I couldn't find many good options that were fast, responsive, and visual.

    I figured this crowd would be interested in tech stack as well, it's using arquero [1] bindings over apache arrow for in-memory analytics, and visx [2] for visualizations. I'd like to add duckdb-wasm support at some point to open up a wider set of databases. Data is serialized as parquet to save a bit on bandwidth + storage.

    Give it a spin, and let me know what you think. This is my first 'serious frontend project' so I appreciate any and all feedback and bug reports. Feel free to comment here (I'll be around most of the day), or shoot me a note: [email protected]
