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.

What Makes This Tool Different

Automatic Column Detection

We look at your JSON objects and figure out all the keys automatically. Those become your CSV column headers. Works perfectly with arrays of objects.

Nested Data Handling

Got nested objects or arrays? We handle them smartly. We convert nested values to strings or flatten them so your CSV stays usable.

Excel Compatible

The CSV we generate works perfectly with Microsoft Excel, Google Sheets, and other spreadsheet apps. Open it directly without any formatting issues.

File Upload Support

Got a big file? Just upload it. Works great for converting those massive JSON exports from databases or APIs without copy-pasting.

Download CSV

One click to download your CSV file. Drop it into any spreadsheet app or use it for data analysis – it's ready to go.

Syntax Highlighting

Nice syntax highlighting makes it easy to check your JSON before converting. Visual feedback helps you spot issues early.

How It Works

Paste or Upload JSON

Paste your JSON array into the left editor, or click "Upload" to load a file. The JSON should be an array of objects (like [{"name":"John","age":30}]). You can also click "Sample" to see an example.

Automatic Conversion

As soon as you paste, the converter processes your JSON and displays the CSV output on the right. Each JSON object becomes a row, and each key becomes a column header.

Download or Copy

Click "Download" to save the CSV file, or "Copy" to copy it to your clipboard. The CSV is ready to open in Excel, Google Sheets, or any spreadsheet application.

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.

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.

Other JSON Tools You Might Need

Conversion is just one JSON task. Here are other tools that work well together:
