What is JSON to CSV Converter?

Need to get your JSON into Excel or Google Sheets? This tool converts your JSON (JavaScript Object Notation) data into CSV format. Great for importing into spreadsheets, doing analysis, or just working with your data in a way that makes more sense.

As MDN Web Docs notes, CSV is one of the most widely supported formats out there. Our converter takes JSON arrays of objects, figures out all the keys as column headers, and turns each object into a CSV row. Works great with API data, database exports, or config files.

Everything happens in your browser – your data stays private. Convert, download, and use your CSV file right away. Check out the JSON for more details.

How to Use JSON to CSV

Follow these steps to convert JSON to CSV for Excel and spreadsheets. Each step uses the actual buttons and panels on this page.

Paste JSON Array or Upload

Paste a JSON array of objects into the left JSON Input panel, or click Upload to load a file. Click Sample to see an example. Input format:

[{"subscriberId": "SUB-1001", "plan": "Unlimited 5G", "dataUsage": 45.2}, {"subscriberId": "SUB-1002", "plan": "Family Plan", "dataUsage": 120.5}]

Keys become column headers; each object becomes a CSV row. Nested values are flattened or stringified.

View CSV Output

The right CSV Output panel shows the result automatically. Compatible with Excel and Google Sheets. Invalid JSON will show an error.

Download or Copy

Click Download to save the CSV file, or Copy to copy to your clipboard. Use Clear on the input panel to start over. All processing runs in your browser.

When You'd Actually Use This

Data Analysis

Convert JSON API responses or database exports to CSV for analysis in Excel. Great for creating pivot tables, charts, or doing calculations on your data.

Excel Import

Import JSON data into Excel or Google Sheets. Many business users prefer working with spreadsheets, and CSV is the universal format for data import.

Data Migration

Migrate JSON data to systems that require CSV format. Many legacy systems, reporting tools, or data warehouses accept CSV imports.

Sharing with Non-Developers

Share JSON data with team members who don't work with code. CSV files open in Excel, making data accessible to everyone without technical knowledge.

Common Questions

Is my JSON data stored?

Nope. Everything happens right in your browser. Your JSON never leaves your computer – we don't even see it. Check out the ECMA-404 standard for more details.

What JSON formats work?

The converter works best with JSON arrays of objects, like [{"key":"value"},{"key":"value"}]. Single objects are also supported. Nested objects are converted to strings.

How are nested objects handled?

Nested objects and arrays are converted to JSON strings in the CSV cells. This preserves the data structure while keeping CSV format valid. You can parse them later if needed.

Can I convert CSV back to JSON?

Yep. Use our CSV to JSON converter to convert CSV files back to JSON format.

What if my JSON has different keys?

The converter collects all unique keys from all objects and creates columns for each. Objects missing certain keys will have empty cells in those columns.

Does it work with large datasets?

Yep. Since everything happens in your browser, it depends on your device. Small datasets convert instantly. Really huge datasets (thousands of rows) might take a few seconds.
