Frequently Asked Questions
Does this JSON tool validate my input first?
Yes. Invalid JSON is flagged with an error before any formatting, conversion, or code generation runs, so you know exactly what to fix.
Is my JSON data uploaded anywhere?
No. JSON tools on Alexonic run entirely in your browser — the data you paste never leaves your device or touches a server.
Can I use this on large JSON files?
Small to medium payloads (a typical API response or config file) work well. Very large files can slow down the browser tab since parsing happens client-side.
Why does the generated code need review before use?
Code and model generators infer types from example data, so edge cases like nullable fields, mixed arrays, or unusual date formats may need a manual adjustment before the output goes into production.
