Remove a specified number of leading header rows from a CSV or TSV file and download a newly generated delimited file. Everything runs locally in your browser.
The selected leading records are removed after delimiter-aware parsing. Remaining fields are quoted correctly when the new delimited file is generated.
The original file is never overwritten, and no file contents are uploaded by this page.
CSV and TSV are supported with UTF-8 text. Other encodings should be converted to UTF-8 first; malformed quoting is reported rather than guessed.
| Format | Use |
|---|---|
| XLSX / XLS | Workbook input |
| CSV / TSV | Delimited table input or output |
| JSON | Optional result export |

Formula handling depends on the operation. Formula-inspection tools retain formula text, while rebuilt data outputs may not preserve every Excel feature.
It checks file size and limits the on-page preview. Very large or complex workbooks may still exceed the browser’s available memory.
Browser spreadsheet libraries cannot preserve every advanced Excel object. Open the output and verify important values, formats, and business rules before relying on it.
