Is a JSON beautifier the same as a JSON formatter?

Yes. JSON beautifier, JSON formatter, JSON pretty printer, and JSON indenter all mean the same thing — adding whitespace to make JSON human-readable.

Can I choose how many spaces the beautifier uses?

Yes. FixTools lets you choose 2-space, 4-space, or tab indentation.

Does beautifying JSON affect performance in my app?

Beautified JSON has more bytes due to whitespace, so it is slightly larger. Use the Minify JSON tool to compress it back before sending it over a network.
