About TSV

TSV (tab-separated values) works like CSV but separates columns with tabs, which makes it the format you get when copying cells out of Excel, Google Sheets or a database client.

Private by design

Developer data is often sensitive: API responses, tokens, customer records, internal configs. This TSV Viewer processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.
