TSV (Tab-Separated Values) is a plain-text format where each row is a line and each column is separated by a tab character. It is a common export format from spreadsheets and databases.

TOML (Tom's Obvious, Minimal Language) is a configuration file format designed to be easy to read. It uses key = "value" pairs and supports arrays of tables with [[table-name]] headers.

Does this tool send my data anywhere?

No. The conversion runs entirely in your browser using JavaScript. Nothing is uploaded to any server.

How are data types handled?

Values that are valid integers or floating-point numbers are written unquoted. Everything else is written as a quoted TOML string. Boolean true/false values are also written unquoted.

What if my TSV has no header row?

The first row is always used as the header. If your data has no header, add one manually before pasting, or the first data row will be used as key names.

Summary

Paste tab-separated values and instantly convert them to TOML format in your browser — no upload, no server.

How it works

Paste your TSV data (or upload a .tsv file) into the input panel.
The first row is treated as the header and becomes the TOML key names.
Each subsequent row is converted to a [[records]] table entry in TOML.
Numeric values are written unquoted; everything else is quoted as strings.
Click Copy to clipboard to grab the generated TOML output.

Use cases

Convert exported spreadsheet data to TOML config files.
Migrate TSV datasets into TOML-based static-site generators.
Quickly inspect TSV structure in a more readable key-value format.
Prepare seed data for Rust or Go apps that consume TOML configs.
Validate column names before importing into a TOML-driven pipeline.
