Drop CSV Viewer bởi soyasis

Read local CSV and TSV files without links or a spreadsheet app.

Just drop it in
Drag a .csv or .tsv onto any open Firefox tab and it opens as a clean table in a new tab. No URL, no upload, no "open file" dialog, no Excel.

Features
- Type to filter across all columns
- Click the ▼ next to a column to sort (numbers sort as numbers)
- See live Sum, Average, Min, Max, Count and Unique
- Copy any selection with ⌘/Ctrl-C to paste straight into Sheets or Excel
- Drag a column's right edge to resize; sticky header and first column
- Download the current view (filter + sort applied) back to CSV

Private by design
- 100% local: no network requests, no analytics, no data collection
- Open source (MIT) — read every line on GitHub
- Light & dark, follows your system theme (or toggle it)
