CSV Cleaner trims whitespace from every cell, removes fully empty rows (empty lines) from CSV data, and can drop duplicate rows while preserving quoted fields.

How do you use the csv cleaner tool?
1. Add your text.Paste it directly, upload a file, or drop a TXT/CSV/JSON file onto the input box.
2. Adjust the options.Use the controls above the editor to fine-tune how the tool behaves.
3. Copy or download the result.Your cleaned text is ready instantly, with nothing ever sent to a server.
Need to remove duplicate lines too? Try the full Text Dedupe, which adds case-insensitive matching, consecutive-only mode, sorting, and large-file support.
Yes - the "Remove empty rows" option (on by default) drops any row where every cell is empty, which is what an empty line looks like in CSV data.
Will it also remove duplicate rows, or just empty ones?
Both, if you leave the defaults on. "Remove duplicate rows" and "Remove empty rows" are separate toggles, so you can turn either off independently if you only want one.
What happens to rows with only some empty fields - are those touched?
They're kept. Only rows where every cell is empty get removed - a row with a mix of filled and empty cells is left in place (with whitespace trimmed from its cells if that option is on).
Can I turn off cell trimming if I want to keep the original spacing in my data?
Yes - "Trim cell whitespace" is an independent toggle, so you can disable it while still using the empty-row and duplicate-row cleanup.
