Frequently Asked Questions
How does the validation work?
We parse the string using standard JSON validation protocols. If a syntax error is present, the parser identifies the line number and character offset of the error.
Is it safe to format sensitive APIs here?
Yes. Processing is completed 100% locally in your browser, keeping your data confidential.
