Hi, I wanted to share a JavaScript project that I have been working on during the quarantine period.

It's an Excel/Google Sheets-esque Grid that can be used in your React projects. Some of the features are

1. High performance using canvas 2. Custom Cell renderers and editors 3. Windowing - Only visible cells are renderers 4. Frozen columns and rows 5. Autofilter 6. Import/Export from excel and csv files 7. Styling, Conditional formatting..

I have been working on DataGrids for the last 3 years professionally and I have always wanted to create a product around this.

Hope you like it. Would love to get some feedback :)

R1C1 addressing?

3. Windowing: could this potentially be used as a frontend to a huge database of, say, millions of rows?

Yes to both. Number of rows and columns does not impact performance. Every calculation is within the viewport bounds
