Overview

JSON Formatter

Formats, minifies, and validates JSON data with syntax highlighting and error detection. Used by developers to debug API responses, clean up config files, and ensure JSON validity before deployment.

Best for:

✓ Pretty-printing minified API responses
✓ Validating JSON syntax before sending to APIs
✓ Minifying JSON for production config files
✓ Debugging nested JSON structures

JSON to CSV Converter

Converts JSON arrays or objects into CSV (comma-separated values) format for use in spreadsheets, databases, and data analysis tools. Flattens nested structures and handles arrays intelligently.

Best for:

✓ Importing API data into Excel or Google Sheets
✓ Converting JSON logs to CSV for analysis
✓ Preparing JSON data for database import
✓ Creating reports from JSON API responses

Real Usage Examples

JSON Formatter

Input

{"name":"John","age":30,"city":"New York"}

Output

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

Output

name,age
John,30
Jane,25

When to Use Each Tool

Use JSON Formatter when...

Use JSON Formatter when you need to read, debug, or validate JSON data — for example, pretty-printing a minified API response to understand its structure, or checking if a config file has valid syntax.

Use JSON to CSV Converter when...

Use JSON to CSV when you need to analyze JSON data in a spreadsheet or import it into a database — for example, converting an API response of user records into a CSV file for Excel analysis.

Use both together when...

A common workflow is: paste raw API data into JSON Formatter to validate and understand the structure, then use JSON to CSV to export the data for analysis in a spreadsheet.

Try Both Tools Free

Both tools run entirely in your browser — no signup, no data collection, no limits.

Frequently Asked Questions

When should I use JSON Formatter vs JSON to CSV?

Use JSON Formatter when you want to keep the data as JSON but need to read or validate it. Use JSON to CSV when you need tabular data for spreadsheets, databases, or data analysis tools.

Can JSON Formatter convert JSON to other formats?

JSON Formatter focuses on formatting and validating JSON — it outputs JSON. For format conversion (JSON to CSV, YAML, XML), use a dedicated converter tool like our JSON to CSV converter.

What happens to nested JSON when converting to CSV?

Nested objects are flattened into dot-notation columns (e.g., address.city). Arrays may be joined or expanded depending on the converter. Our JSON to CSV tool handles common nesting patterns automatically.

Can I convert CSV back to JSON?

Not directly with these tools. You would need a CSV-to-JSON converter (available in many programming languages). The JSON Formatter can then validate the resulting JSON.
