About converting JSON5 to JSON
Use this free JSON5 to JSON converter to change JSON5 files into JSON without uploading anything, installing software or signing up. JSON5 extends JSON with comments, trailing commas and unquoted keys - far friendlier to hand-edit, but not understood by standard JSON parsers. JSON is the default data-interchange format of the web: nested objects and arrays that every language parses natively, and humans can still read.
Converting JSON5 to JSON is everyday plumbing work: an export from one system arrives in the wrong shape for the API, script or spreadsheet that has to consume it next.
Because every conversion runs on your own device through WebAssembly builds of the same open-source engines desktop tools use, there is no upload queue, no file-size cap imposed by a server, and no copy of your JSON5 sitting in someone else's storage afterwards. That matters most for anything you would hesitate to hand to a third party - identity documents, contracts, medical scans, unreleased work, client material. It also means the converter keeps working with no network connection at all once the page has loaded.
JSON5 to JSON is one of many routes available here. If a direct path between two formats does not exist, the converter automatically chains several conversions together to reach the one you asked for, so you can get from almost any input to almost any output in a single step.

Frequently asked questions
- Is this JSON5 to JSON converter free?
- Yes, completely. There is no charge, no account, no watermark on the output and no daily conversion limit.
- Are my files uploaded to a server?
- No. The conversion runs in your browser using WebAssembly, so your JSON5 file never leaves your device and nothing is stored anywhere after you close the tab.
- Is there a file size limit for JSON5 to JSON conversion?
- There is no server-imposed limit, because there is no server involved. The practical ceiling is your own device's available memory, so very large files convert faster on a desktop than on a phone.
- Will the JSON output look the same as the JSON5 original?
- JSON output preserves the content of your JSON5 file. Formatting fidelity depends on how closely the two formats can represent the same structures - features one format supports and the other has no equivalent for cannot be carried across.
