How to Use This Tool
Paste your JSON array (e.g. [{"name":"Alice","age":30},{"name":"Bob","age":25}]). Click Convert to CSV. Download the file and open it in Excel or Google Sheets. Headers come from your JSON keys.

PDF Tool →Frequently Asked Questions
What JSON structure works with the converter?
An array of objects where each object shares the same set of keys. The first object's keys become CSV headers. Single objects (not wrapped in an array) are also supported.
How are commas inside JSON values handled?
Values containing commas are wrapped in double quotes in the CSV output, following RFC 4180. Excel and Google Sheets both handle this correctly without any extra configuration.
Can I convert JSON to TSV (tab-separated) instead?
The current tool outputs comma-separated CSV. To get TSV, download the CSV, open it in Excel, and save as Tab Delimited Text format.
