JSON to TOML Converter

Translate configuration data from JSON to TOML

JSON and TOML can express many of the same configuration values, but they organize nested data differently. This converter parses a JSON object, writes top-level scalar values first, and emits nested objects as TOML tables. Strings are quoted and escaped, numbers and booleans remain unquoted, null becomes an empty string, and scalar arrays retain their item order. Invalid JSON and unsupported object values inside arrays produce a visible error instead of partial output.

The default sample contains a title, count, active flag, two tags, and an owner object. Its TOML output begins with title equals Example, count equals 3, active equals true, and a two-item tags array. A separate owner table then contains name equals Ada. That concrete structure makes it easy to compare the original hierarchy with the generated table notation before replacing an application configuration file.

Convert sensitive settings without uploading them

Parsing and formatting happen in your browser, which is useful for configuration text that may contain internal names or local settings. Still review the result against the TOML parser used by the target application. This focused converter does not emit arrays of tables, date literals, custom numeric types, or comments, and converting formats cannot preserve comments that were absent from the original JSON data model.
