Frequently Asked Questions

What’s the difference between Convert and the Pretty button?

Convert (JSON → JSON) sends your input to the server and returns pretty-printed JSON in the Output panel. The Pretty button reformats the Input panel itself, in place, without touching the Output panel.

What if my JSON has a syntax error?

Use the "Check & Suggest Fix" button (or see the JSON Validator) to get the exact line and column of the problem before formatting.
