A CSV cleaner that fixes the things that break imports: trims whitespace in every cell, collapses double quotes, normalizes line endings to \n, removes empty rows, dedupes rows by any column, and escapes stray commas inside fields. Drop a file or paste CSV, toggle the rules you need, and copy the cleaned output.

Pair with CSV viewer to check the before/after, or CSV to JSON if you need the cleaned data in JSON. When the file's really tab-separated, start with TSV to CSV.

Nasıl Kullanılır

Drop your CSV file or paste rows.
Turn on the cleanups you need — trim, dedupe, normalize line endings.
