JSON to CSV Converter
Flatten complex JSON arrays into clean CSV spreadsheets. Easily import data from web APIs into Excel or Google Sheets.
Why Convert JSON to CSV?
JSON is the language of the web, used by almost every modern API to send data. However, analyzing this data usually happens in spreadsheets. Converting JSON to CSV bridges this gap, allowing you to take raw data from a server response or database export and instantly view it in Microsoft Excel, Apple Numbers, or Google Sheets.
Our tool intelligently handles the structure of your JSON files, including nested objects and arrays. It identifies keys to use as column headers and maps values to the correct rows, saving you hours of tedious manual copy-pasting, complex script writing, or debugging custom data transformation pipelines.
How to Convert JSON to CSV
- Upload your .json file containing an array of objects.
- The converter parses the keys to create column headers.
- Click 'Convert' to flatten the data structure.
- Download the .csv file for immediate use in Excel.

Frequently Asked Questions
Can it handle nested objects?
Yes, our converter attempts to flatten nested objects by combining keys (e.g., 'user.address.city') to ensure all data is preserved in a tabular format.
What if my JSON is not an array?
Ideally, the input should be an array of objects. If you provide a single object, the converter will generate a CSV with one row of values.
Is the conversion private?
Absolutely. All data processing happens securely on our servers, and your uploaded files are permanently deleted from our systems immediately after the conversion is complete.
Will large files crash the browser?
We manage large datasets efficiently on the server side, allowing you to convert substantial JSON exports without freezing your computer.
