What this conversion produces
Clean a JSON5 configuration for a program that accepts only strict JSON. The parser supports familiar JSON5 conveniences such as comments, trailing commas and quoted or unquoted object keys, then writes a consistently formatted JSON document. This is useful when moving a development configuration into a stricter import interface.
Supported input and practical limits
Only values that strict JSON can represent are accepted. Non-finite numbers and unsafe integer magnitudes are rejected rather than silently converted to null or rounded. Comments and original formatting are intentionally discarded in the output. Duplicate object keys follow the JSON5 parser’s last-value behavior, so review configurations where repeated keys may be significant. Input is limited to 2 MiB of text with bounded object depth.
Example input
// Development settings
{ app: 'Utilixio', enabled: true, ports: [3000, 3001,], }What should I know before converting?

Is input uploaded?

No conversion history is saved. The converter does not upload files to a third-party conversion service.
