What is the Code Formatter?
The IPerfect.Net Formator tool is a free online code formatter and validator for the most common data formats and languages. Paste in minified, messy, or hard-to-read code and it will instantly format it with proper indentation and structure — making it easy to read, debug, and share. No installation, no account.
Open JSON Formatter
JSON Formatter — Example
Paste minified JSON and the formatter will expand it into a readable, properly indented structure. It also validates the JSON and highlights any syntax errors.
Input (minified)
{"name":"Neeraj","role":"developer","tools":["notepad","ping","converter"]}
Output (formatted)
{
"name": "Neeraj",
"role": "developer",
"tools": [
"notepad",
"ping",
"converter"
]
}
How to Use the Formatter
- Open IPerfect.Net and go to the Formator & Replacer tab.
- Select the format type (JSON, XML, SQL, CSS, or JS).
- Paste your code or data into the input panel.
- Click Format. The formatted result appears instantly in the output panel.
- Copy the output or use the built-in editor to make further edits.
Find & Replace (Bulk Replacer)
The Formator tab also includes a Bulk Replacer tool that lets you perform multiple find-and-replace operations on any block of text in one pass. This is useful for:
- Renaming variables or keys across a large JSON or config block
- Replacing placeholder values in template files
- Cleaning up exported data before importing it elsewhere
Why Use an Online JSON Formatter?
When working with APIs, configuration files, or databases, data is often returned in a compact, single-line format to save bandwidth. An online formatter lets you:
- Read it easily — see the nested structure clearly without counting braces.
- Find bugs faster — formatting reveals mismatched brackets, missing commas, or wrong types at a glance.
- Share it clearly — paste formatted code into a bug report or code review so reviewers don't have to parse minified text.
- No install needed — works on any computer or phone without plugins or editor setup.
