About CSV Filter

The CSV Filter keeps only the rows that match a condition you define on a column — equals, contains, greater than, and more — and drops everything else. It's the fast way to pull a segment out of a large export without loading it into a database or spreadsheet. Filtering runs locally in your browser, so sensitive data never leaves your device. Combine it with the CSV Column Extractor to also trim columns, or the CSV Sorter to order the results.

How to Use

1Open CSV Filter and paste or type your data into the input area.
2Adjust any available options to match the result you want.
3Your output is generated instantly — no button-clicking required for most tools.
4Use the Copy or Download button to save your result.

Common Use Cases

Inspecting exports from spreadsheets, databases, and analytics tools
Cleaning and reshaping CSV data before importing it elsewhere
Converting tabular data between CSV, JSON, TSV, and Markdown
Validating delimited files before a bulk upload or migration

Frequently Asked Questions

What conditions can I filter on?

You can match rows where a column equals, contains, or compares against a value, so you can extract records like a specific status, a name substring, or a numeric threshold.

Can I combine filters?

Yes. Apply a filter, then filter the result again, or chain with the Column Extractor and Sorter to build up exactly the subset of data you need.

Is CSV Filter free to use?

Yes. CSV Filter is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use CSV Filter?

Absolutely. CSV Filter runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
