About this tool
About this tool
CSV Filter keeps only rows matching a condition on a selected column by evaluating equals, contains, greater than, and similar operators locally in your browser. Filtered results are shown instantly for review before export.
Filter CSV records by column, operator, and search value. Use the full-width workspace to filter content while reviewing rows, columns, headers, delimiters, and values. The tool accepts CSV, provides focused options, and creates CSV output that you can inspect, copy, download, or save as a local draft.
Built for daily work
- Use CSV Filter for data imports, spreadsheet cleanup, reporting, and database preparation.
- Keep or remove records that match the selected condition before content is imported, published, committed, shared, or passed to another application.
- Check a small sample interactively before applying the same operation to a larger tabular data workflow.
- Prepare cleaner CSV output for teammates, clients, documentation, testing, or downstream automation.

Export or continue the workflow
Copy or download the CSV result, save a browser-local draft, or open a related tool for the next conversion, validation, or cleanup step.
Key features
Key features
Column and operator-based filtering
Select a column, pick a comparison operator such as equals, contains, starts with, greater than, or less than, and enter a value to build a precise row filter.
Keep or exclude matching rows
Switch between keep mode (only matching rows pass through) and exclude mode (matching rows are dropped) to quickly invert your selection without re-entering the condition.
Match count and filtered preview
The report shows how many rows matched the condition and how many were removed, and the workspace displays only the rows that passed the filter for immediate review.
Download the filtered subset
Copy or download only the rows that matched, with headers intact, so the exported file is ready for analysis, import, or the next processing step.

Limitations and important notes
- Confirm filters on a sample before applying them to an important dataset.
