How does in-browser JSON validation work?

The parser processes your text directly in client-side memory using native JavaScript parsing APIs. It calculates character offsets, line counts, and column positions to display the precise syntax error location when formatting fails.

Does the formatter upload my JSON to a server?

No data is uploaded over the network. The validator executes entirely within your local browser runtime memory sandbox, ensuring sensitive configuration files, API payloads, and tokens remain on your local machine.

Can this tool repair malformed JSON syntax?

Yes. The auto-repair feature corrects common syntax mistakes such as trailing commas, single-quoted keys, unquoted object properties, and JavaScript object literals.

What indentation options are supported?

You can format JSON with 2 spaces, 3 spaces, 4 spaces, tab indentation, or minify the output into a single compact line for network payload optimization.
