Common situations

Start from what you need to do

Validation finds broken syntax

If a payload is missing quotes, commas or brackets, validation is the first thing you need. A readable error location saves time immediately.

Formatting improves review speed

Once the JSON is valid, formatting makes nested objects and arrays easier to inspect, compare and share with teammates.

One page can handle both tasks

A browser JSON tool is more efficient when it can validate, pretty-print, minify and sort keys without forcing you to switch pages.

Steps

1 Start by matching your situation with the problem cards below.

2 Open JSON Formatter and fix the issue directly on the tool page.

3 After that, verify the output and continue into the next step if needed.

FAQ

Should I validate or format first?

Validate first. If the JSON is invalid, formatting usually cannot continue.
