About this conversion
This tool converts Excel files to TSV format directly in your browser — no account required, no file upload, no waiting for a server. It processes your data entirely within your browser using WebAssembly, so nothing ever leaves your device.

Frequently Asked Questions
What is TSV format?
TSV (Tab-Separated Values) is similar to CSV but uses tab characters as delimiters — useful when data values contain commas.
Is my Excel data private?
Yes — completely. Your file is never uploaded to any server. All conversion happens inside your browser using WebAssembly — locally, with no upload. 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 can handle 500 MB to 1 GB comfortably.
What is the difference between Excel and TSV?
Both Excel and TSV are common data formats used in engineering and analytics workflows.
