TSV uses a single tab character between columns and a new line between rows. Copying a selection from a spreadsheet produces TSV, which makes this tool handy for quick paste-and-convert workflows.

How are numbers and booleans handled?

When the parse option is enabled, cells that look like numbers (such as 42 or -3.5) become JSON numbers, and true/false become JSON booleans. Everything else stays a string.

No. Parsing happens entirely in your browser; nothing is sent to a server.

What is TSV to JSON Converter?

TSV (tab-separated values) is what you get when you copy cells from Excel, Google Sheets, or Numbers. This converter turns that into structured JSON: with the header option on, each row becomes an object keyed by the first row's column names; with it off, each row becomes an array of values.

The optional number and boolean parsing converts cells like 42 and true into real JSON numbers and booleans instead of strings. Everything runs in your browser, so even sensitive spreadsheet data stays private.
