TOML Viewer

Open a TOML file and read its tables and values. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.

How to do it

  1. Drop your TOML file onto the box, or paste it.
  2. Read the structure below.
  3. Use the search box to find a value.

Questions

What is TOML used for?

Configuration — Cargo.toml, pyproject.toml, Hugo sites. It exists because YAML’s flexibility turned out to be a liability.

Why is my date shown as text?

Because TOML has a date type and JSON does not, and converting it through a date object would rewrite 1979-05-27T07:32:00-08:00 into a different offset — the same instant, a different document. Keeping the text keeps the document.

What about very large numbers?

TOML allows 64-bit integers and a browser holds 53 bits exactly, so anything larger is kept as digits rather than rounded to a number that is not the one you wrote.
