TOML Config Example: Valid Server Settings with Tables and Arrays

This page opens the TOML validator preloaded with a small, realistic configuration file: top-level metadata keys including an inline tags array, a [server] table with a nested [server.limits] sub-table, and a repeated [[plugins]] array-of-tables block listing two plugin entries. The pass result below is computed the instant the page loads, using the same parsing rules as any file you paste in.

TOML's table and array syntax is where hand-written config files most often go wrong, so this example is built to exercise the parts that matter: a dotted sub-table name, an inline array with a trailing bracket on the same line, and the double-bracket [[...]] syntax that TOML uses specifically to allow a table header to repeat — the one case where the same header appearing twice is not an error. It mirrors the shape of a real Cargo.toml, pyproject.toml or application settings file.

Paste your own TOML into the box to check it the same way. If a single-bracket table header like [server] is accidentally repeated, or a key is duplicated inside the same table, the validator reports the exact line — the same class of mistake demonstrated on the duplicate-table-error preset page.
