Convert JSON arrays to clean CSV with headers and custom delimiters.

Convert Data

Examples

JSON Input (Array of Objects):

[
  {"name": "John Doe", "age": 30, "city": "New York"},
  {"name": "Jane Smith", "age": 25, "city": "London"}
]

CSV Output:

name,age,city
John Doe,30,New York
Jane Smith,25,London

What It Does

JSON to CSV Converter turns JSON arrays of objects into clean, spreadsheet-ready CSV. It auto-detects keys as columns, escapes commas/quotes/newlines correctly, and lets you choose whether to include a header row or pick a custom delimiter.

Key Features:

  • JSON array → CSV rows with optional header row
  • Auto-collects keys across all objects into unified columns
  • RFC 4180-style escaping for commas, quotes, and newlines
  • Custom delimiter support (comma, semicolon, tab, or custom)
  • Keeps missing fields empty instead of dropping columns

Pro Tips

  • •Ensure input is a JSON array of objects for best results
  • •Use semicolon or tab delimiter if your data contains many commas
  • •Headers are usually recommended so downstream tools name columns
  • •Arrays or nested objects are serialized as JSON strings inside cells

Benefits

Move API/JSON responses into Excel or Sheets fast
Prepare JSON exports for database CSV imports
Share tabular data without exposing nested JSON complexity
Keep column order consistent across mixed objects

Use Cases

API data to spreadsheet

Transform JSON API responses into CSV for analysts and PMs.

Input: [{"id":1,"name":"John"},{"id":2,"name":"Jane"}] → CSV rows

DB export normalization

Convert JSON exports to CSV for bulk import into relational databases.

Reporting handoff

Deliver CSV extracts to stakeholders who prefer spreadsheets.

Frequently Asked Questions

1 What input works best?
A JSON array of flat objects. Nested objects or arrays are serialized as JSON strings so the CSV stays valid.
2 How are headers chosen?
All keys from every object are collected into one header row; missing keys in a row become empty cells.
3 How are commas or quotes handled?
Fields with commas, quotes, or newlines are wrapped in quotes and internal quotes are doubled, following RFC 4180.
