About this tool
Split large TSV files into smaller chunks by row count. Each output file is a valid TSV file with the same headers. Useful for working with tools or APIs that have row limits.
Frequently Asked Questions
How does the TSV file splitter decide where to cut?
It divides rows evenly into chunks of the size you specify. If the file does not divide evenly, the last chunk contains the remaining rows.
Do the split TSV files include column headers?
Yes. Every output file gets the same column headers as the original, so each chunk is a valid standalone file.
What format are the output files when I split a TSV file?
The output format matches the input — splitting a TSV file produces multiple TSV files, one per chunk.
Is my data private?
Yes — completely. Your file is never uploaded to any server. Everything runs locally in your browser using WebAssembly — processing happens entirely inside your tab. Once you close the tab, nothing is retained.
What is the maximum file size?
The free limit is 50 MB. For larger files, performance depends on your device's available memory — most modern machines handle 500 MB to 1 GB comfortably.
