CSV Row Filter

CSV Row Filter

Use this tool to query CSV files without writing SQL or loading a spreadsheet app. Select any column, pick a condition (contains, equals, starts with, ends with, greater than, less than, is empty, or regex), enter a value, and choose whether to keep or remove matching rows. The filtered result retains the original header row and can be copied or downloaded as a new CSV file. Supports files up to 25 MB via drag-and-drop upload. All processing runs entirely in your browser — no data is uploaded to any server.
