How to use INI / JSON5
- 1. Paste or drop a file. INI, properties, JSON, JSONC, or JSON5 is read locally.
- 2. Pick the source format. JSONC is treated as JSON5 after comments are stripped.
- 3. Choose the target. JSON, INI, properties, or JSON5.
- 4. Copy the result. Parsing stays in this tab.
About this tool
Config files still ship as INI, Java properties, JSONC, and JSON5. This tool round-trips the common subset in the browser so a dotenv-style map, a Win32 INI, and a commented JSON blob can share a payload without a server.
What round-trips
Flat keys and INI sections become JSON objects. Nested JSON becomes a best-effort INI. JSONC comments are stripped before parse. Trailing commas and unquoted keys are JSON5.
What does not
INI duplicate keys, interpolation, and Windows code pages are out of scope. Review output before you commit it.
