How to use it in three steps

The tool as a schematic with this page's example. Each step's number stands where you take it: in the fields, at the result or outside the tool.

JSON formatter
What you enter
{"name":"VulCode","active":true,"services":["vulbio","flaem"]}

  1. Paste the JSON.

  2. Choose pretty-print or minify.

What you get
{ "name": "VulCode", "active": true, "services": [ "vulbio", "flaem" ] }

  1. Copy the result, or fix the error at the given line and column.

Six inputs through the JSON formatter

An error, an empty field, how numbers are written, a repeated key and a large integer. The last row shows a JavaScript limit: keep Discord IDs in JSON as quoted text.
