Comment on: Show HN: Extend UI – open-source UI kit for modern document apps

Thanks, that looks awesome! We were looking to add DOCX and XLSX preview to our app, and were planning to do server-side conversion to PDF (which seems to be what most other apps resort to) due to the lack of good libraries to render it, and this is exactly what we were looking for! :)

Comment on: Show HN: Display Excel files in your web app

Ahh this would've been so usefulI recently made an internal tool for my business where I could upload Excel inventory files and I ended up parsing everything natively then rebuilding the preview with UI tables. Never even crossed my mind that someone would've built a component just for this haha.How does it perform with larger workbooks (say 20–50MB or hundreds of thousands of cells)?cDoes it virtualize rendering, or does it load the entire workbook into memory upfront? We typically get auction lists every week which is around 20-30 MB.

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
