Frequently asked questions

What indentation levels are supported?

Any positive integer works, though 2 and 4 are the most common. The default is 2 spaces.

Does formatting change the data in any way?

No. The output is semantically identical to the input. Only whitespace and line breaks change.

What happens if the input JSON is invalid?

The API returns an error with the parse failure location, so you can fix the syntax issue.

Can I format JSON with tab indentation instead of spaces?

The API currently supports space-based indentation only. Set the indent parameter to your preferred number of spaces.
