CSV Filter
Keep only the CSV rows where a column matches a condition — equals, contains, greater/less than, empty, and more.
About CSV Filter
CSV Filter keeps only the rows where a chosen column matches a condition — equals, contains, greater than, less than, empty, and more. It is the quick way to slice a large export down to the subset you actually care about without opening a spreadsheet app. Everything runs in your browser, so your data stays on your machine.

Frequently asked questions
Is my CSV sent to a server?
No. The filtering logic runs locally in your browser, so no upload happens.
What conditions are supported?
Equals, contains, greater-than, less-than, empty, and similar comparisons against a single column's value.
Does the header row survive filtering?
Yes. The header is kept and only matching data rows are returned.
Can numeric comparisons handle real numbers?
Yes. Greater-than and less-than compare the column numerically, so 1000 ranks above 999.
What comes out the other end?
A CSV containing only the rows that passed your condition, in their original order.
