Thank you for writing this. It resonates with me at this moment in my life! :-)

Thanks for your comment!
It will handle 100,000s of cells without much issues: it has virtualized scrolling and rendering .
I have not tested it with large file sizes, like your 20mb or 50mb examples.
I would love to test the product with it. Is there a way you could send us an example of such a workbook, where data is anonimized?
You can send it to [email protected]

I am working on Spreadsheet Preview, embed and preview Excel files in any website/web app. Just like PDF.js for pdf files. Check it out at https://spreadsheetpreview.com

Hello Hacker News!
I have just launched SpreadsheetPreview, an embeddable Javascript/Typescript component that displays an Excel file (.xlsx) in any browser.
Benefits: No upload. No server. No Microsoft Office dependency.
You can see it here: https://spreadsheetpreview.com.
The component is based on DataGrid Toolkit, the toolkit that also powers upcoming DataGridXL v4, which is an editable data grid component with an Excel-like interface.
The component is free to use for non-commercial projects. Commercial use requires license.
Please try it out and let me know what you think!
Best,
Robbert

Cool game! Reminds me of the untitled Goose Game, bullying citizens, is that a genre? It should definitely be a genre.

I am working on SpreadsheetPreview.com, a subscription service that gives you PNG previews of your uploaded spreadsheet (xlxs files).
On the server it opens a headless browser, where it converts the XLXS format to OGF (Open Grid Format), which is then rendered by DataGrid Toolkit, the engine behind DataGridXL v4. It then takes a screenshot of this render and sends it back to the requester.
Try out a few renders at https://spreadsheetpreview.com

I am working on a browser plugin that lets you edit Supabase database tables just like Excel, until it's ready. Then you switch to the main branch and the tables will be read only

I am working on a platform called ikverdienbeter.nl (i deserve better) that educates people on recognizing healthy behaviour and healthy boundaries. I take snippets from popular tv, like dating shows, and mark the "red flags" on a timeline. For instance: "here at time 1:05 you see the woman gaslight the man. Gaslighting means [...]".
Using AI for auto subtitles and actor matching. Will build some auto deploy fragment to social media as well. I think these short fragments will do well op TikTok.
