csv.gripe

Open, view and edit CSV files. Nothing is uploaded.
Drop a CSV here, or click to choose
CSV, TSV or any delimited text, big files too (50 MB / 500k rows is fine) · or paste with Ctrl+V / ⌘V

Opening a CSV shouldn't need Excel, or uploading it to some converter site. This reads the file right here in your browser: sort, filter, edit, find & replace, remove duplicates, see column stats, and export to CSV, TSV, JSON, Markdown, HTML or SQL. Working with JSON instead? Try json.gripe.

Columns

Untick to hide, use the arrows to reorder (or drag the column headers). Double-click a header to rename it.

Find & replace

With a regular expression, use $1, $2… in the replacement for captured groups.

Remove duplicate rows

Rows count as duplicates when all the ticked columns match. The first one is kept.

Each file gets the header row and uses the CSV settings from Export (delimiter, quotes, line endings, BOM). Downloads as one .zip.
