CSV Editor
A small spreadsheet-style editor for CSV (Comma-Separated Values). Paste or drop a file, click Load, then click any cell to edit. Add or remove rows and columns from the toolbar; rename a column by editing its header. Export back to CSV when you're done.

What it's good for
- Fixing a handful of bad cells without opening Excel.
- Renaming column headers across the file.
- Pruning a few rows or columns before handing the file to a teammate.
What it's not for
If you need formulas, conditional formatting, charts, or hundreds of thousands of rows, use a real spreadsheet. This editor keeps every cell in memory and re-renders the whole table on each edit — fast for a few thousand rows, sluggish for tens of thousands.
