}FAQ
Does this send my JSON to a server?+
No. Parsing and formatting run 100% in your browser.
What indent should I use?+
2 spaces is the standard for readability and diffing. 4 spaces is common in older codebases; tab indent works for teams that prefer it.
Can I use this for JSON-LD schema?+
Yes. Paste your structured-data JSON-LD, format it, and verify it parses cleanly before pasting into your <script type="application/ld+json"> tag.
