What is JSON to CSV Converter?
Convert JSON arrays and nested objects into clean, spreadsheet-ready CSV files instantly — no upload, no account required. This browser-based tool flattens nested JSON structures, lets you choose your delimiter (comma, tab, semicolon), and handles arrays of objects as well as single objects. Developers use it to prepare API responses for stakeholder reports; analysts use it to bridge backend data exports with Excel or Google Sheets. Because everything runs locally in your browser, sensitive records never leave your machine. Download the result as a .csv file or copy it directly to your clipboard in seconds.
How to Use
- 1
Paste Your JSON
Paste your JSON array or object into the input panel. You can also drag-and-drop a .json or .jsonl file directly onto the editor, or fetch JSON from a remote URL.
- 2
Configure Options
Choose your delimiter (comma, semicolon, tab, or pipe), toggle header row inclusion, enable force-quoting, and decide how nested objects and arrays should be handled.
- 3
Click Convert
Press "Convert to CSV". The tool parses and transforms your JSON entirely in the browser — no data is sent to any server.
- 4
Download or Copy
Click "Download CSV" to save the file, or "Copy" to paste directly into Excel, Google Sheets, Tableau, or any text editor.
Common Use Cases
Excel & Google Sheets
Excel and Sheets cannot natively open JSON files. Convert your API response or data export to CSV first, then import it directly as a structured spreadsheet.
BI Tools & Dashboards
Tableau, Power BI, and Looker all accept CSV as a primary data source. Transform your JSON data feeds into CSV before loading them into your dashboard.
Database Imports
MySQL LOAD DATA INFILE, PostgreSQL COPY, and most ETL pipelines expect CSV. Use this tool to prepare JSON exports from APIs or NoSQL databases for bulk import.
Legacy System Integration
Older enterprise systems often only support flat file formats. Convert JSON payloads from modern APIs into CSV so they can be processed by legacy software.
Conversion Examples
Array of Objects → Standard CSV
The most common case: a JSON array where each object becomes a row.
Input JSON
[
{"id": 1, "name": "Alice", "role": "Engineer"},
{"id": 2, "name": "Bob", "role": "Designer"},
{"id": 3, "name": "Carol", "role": "Manager"}
]Output CSV
id,name,role 1,Alice,Engineer 2,Bob,Designer 3,Carol,Manager
Nested Object → Flattened CSV
Nested objects are flattened using dot-notation keys.
Input JSON
[
{"id": 1, "name": "Alice", "address": {"city": "London", "zip": "EC1A"}},
{"id": 2, "name": "Bob", "address": {"city": "Paris", "zip": "75001"}}
]Output CSV
id,name,address.city,address.zip 1,Alice,London,EC1A 2,Bob,Paris,75001
Single JSON Object → One-Row CSV
A single object produces a CSV with one header row and one data row.
Input JSON
{"product": "Widget", "price": 9.99, "inStock": true}Output CSV
product,price,inStock Widget,9.99,true
