Frequently Asked Questions

What filter operators are available?

One: case-insensitive contains on a single column. There are no exact-match, numeric-comparison, or not-equal operators.

Can I filter by multiple columns?

No. One column and one value per run — filter once, then filter the result again for a second condition.

Is the filtered output a new CSV?

Yes. The filtered rows are output as a new CSV with the same headers as the original, with copy and download buttons. The source input is not modified.

Does it handle large CSV files?

Filtering runs in browser memory. Very large pastes may slow the tab — for huge datasets, filter in smaller chunks.

Is my CSV data stored or transmitted?

No. All filtering happens locally in your browser. No data is sent to any server.

What happens if I clear the filter value?

Every row matches — an empty string is contained in all values, so the full table returns with the match count equal to all rows. Filtering is always case-insensitive substring on one column per run.
