About this tool

Analysis tools measure text instead of rewriting it — counting words, characters and lines, estimating reading time and readability, or checking whether a string is a palindrome, an anagram or valid JSON — a quick report you read at a glance.

How to use it

  1. Type or paste your input

    Drop your text into the input box. Validate JSON runs on whatever you enter, with no limit and no sign-up.

  2. Read the result instantly

    The output updates as you type, computed on your device with no round trip to a server.

  3. Copy it

    Press Copy to put the result on your clipboard, ready to paste wherever you need it.

Frequently asked

Is my text uploaded anywhere?
No. Validate JSON runs entirely in your browser tab, so whatever you paste stays on your device.
Is there a length limit?
No hard limit. It processes as much text as your browser can hold, and it all happens locally.
Does it work on mobile?
Yes. It runs in any modern mobile browser and keeps working offline once the page has loaded.
