TOML to JSON Converter

TOML to JSON is for lightweight settings files, not the complete TOML spec

This page is useful when a basic TOML snippet needs to move into a JSON workflow for inspection, testing, or another browser-side conversion. It is a practical toml to json step for small configuration files where the syntax stays close to simple keys, primitive arrays, and table sections.

The parser reads key-value pairs, boolean and numeric literals, quoted strings, primitive arrays, and table headers such as [user] or dotted sections. It does not support array-of-tables, datetime typing, inline tables, or full TOML formatting fidelity.

What the current parser returns

Primitive values are mapped into JSON scalars, section headers create nested objects, and primitive arrays become JSON arrays. That makes the output ready for schema drafting, code generation, or another data conversion, as long as the source TOML stays within the supported subset.

ExampleValue
InputA lightweight TOML settings block with basic tables and simple values.
OutputA JSON object that keeps section nesting and primitive arrays.

Where TOML to JSON is genuinely useful

  • Moving a basic TOML config into JSON-based tooling.
  • Checking how table sections map into nested object structure.
  • Preparing a JSON object before schema generation or code scaffolding.

What this page will not parse safely

If the file depends on double-bracket array-of-tables syntax, richer TOML types, or stylistic fidelity, this parser is too small for the job. It is more valuable as a browser toml to json helper for simple configs than as a broad promise to understand every TOML document.

Frequently asked questions

Does TOML to JSON support array-of-tables?

No. The current parser is limited to basic sections and primitive arrays.

Can it parse TOML dates and times as special types?

No. The supported subset focuses on strings, numbers, booleans, arrays, and nested tables.

How are section headers handled?

Headers such as [user] or dotted section names create nested JSON objects.

When should I use a stronger parser?

Use a stronger parser when the TOML file relies on richer syntax than simple settings-style structure.
