How it works
This tool filters the rows of a CSV file based on a condition you specify: choose a column, a comparison operator (equals, contains, greater than, etc.), and a value. Only rows that match the condition are included in the output.
It works like a simple SQL WHERE clause applied to a CSV, entirely in your browser. This is useful for extracting a segment of data — for example, orders from a specific region, entries above a certain dollar value, or records containing a keyword.
Paste or upload your CSV, select the target column from the dropdown, choose a comparison type, and enter the filter value. Download or copy the matching rows including the header.
For more complex filtering involving multiple conditions, consider running a second filter pass on the output of the first.
Worked example
Extract all orders from the West region in a sales CSV
- Upload the sales CSV.
- Select Region from the column dropdown.
- Choose equals as the operator.
- Type West in the value field.
- Click Filter and download the matching rows.
A CSV containing only rows where the Region column equals West, with the original header preserved.
Common mistakes to avoid
- Using equals when the column value has leading or trailing spaces — the match will fail; use contains or trim the source data first.
- Comparing number columns with contains instead of greater than or equals.
- Forgetting that the filter is case-sensitive by default, causing missed matches on mixed-case values.
Key terms
- Filter condition
- A rule that each row is tested against; only rows where the condition is true appear in the output.
- Contains operator
- A filter that matches rows where the selected column's value includes the specified substring anywhere within it.
- Case sensitivity
- Whether uppercase and lowercase letters are treated as different; many filter tools offer a case-insensitive option.
Frequently asked questions
- Can I do numeric comparisons?
- Yes — choose 'greater than' or 'less than'; the cell value is parsed as a number.
- Is anything uploaded?
- No — all filtering runs locally in your browser via PapaParse.
