About JSON to CSV Converter

This tool converts JSON arrays into CSV (Comma-Separated Values) format, making it easy to import data into spreadsheet applications like Excel or Google Sheets.

Features

Nested Object Support: Flattens nested objects using dot notation (e.g., address.city)
Custom Delimiters: Choose between comma, semicolon, or tab
Header Options: Include or exclude column headers
Automatic Escaping: Properly escapes special characters

How It Works

Paste or upload your JSON array
Select your preferred delimiter
Choose whether to include headers
Copy or download the resulting CSV

Input Requirements

The input must be a JSON array of objects. Each object in the array becomes a row in the CSV output, and object keys become column headers.

Example

[
  {"name": "Alice", "age": 30},
  {"name": "Bob", "age": 25}
]

Converts to:

name,age
Alice,30
Bob,25

The Excel Handoff Problem

Your backend speaks JSON. Your PM wants a spreadsheet. This is the story of every data export feature ever built.

JSONLint JSON to CSV handles the edge cases that trip up basic converters — nested objects, arrays within arrays, Unicode characters, and values with commas or quotes that would break naive CSV parsers.
