Code

JSON to Struct is a tool that infers types from JSON, processing runs locally in your browser, so your input never reaches a server.

Results update as you change values; copy or download when ready.

Paste or type your content into the input field at the top, or press the sample button to load demo data.
Adjust the options below the input, such as output format, separators, letter case or precision.
Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
When the result looks right, use the copy button in the corner, or download it as a local file.

Clean up stray spaces and line breaks before pasting for more accurate results.

What about mixed-type arrays?+

When elements differ, the tool picks a type that can hold all values; object arrays merge their fields and mark optional keys.

Is the output production ready?+

Mostly. Adjust field names and package names to your conventions; the Go output includes json tags.

Is JSON to Struct free to use?+

Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.

Is the text I enter uploaded anywhere?+

No. All processing runs locally in your browser, so the input never reaches a server and is never logged or stored.

Does JSON to Struct work on a phone or tablet?+

Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.

Can I copy the result into my own document?+

Yes. A copy button in the output panel puts the result on your clipboard, and you can also download it as a text file.
