THE BASICS

What Is a JSON to CSV Converter?

A JSON to CSV converter turns structured JSON data into rows and columns. Each object in a JSON array becomes a row, and each property becomes a column, so the data opens neatly in Excel, Google Sheets or any database import tool.

It is handy when an API or export gives you JSON but you need a spreadsheet — for reporting, cleaning data, sharing with non-developers or importing into another system.

A few things, answered.

Quick answers about using the MoSanKit JSON to CSV Converter.

Yes. It is free to use, with no account or sign-up.

Usually an array of objects, such as [{"name":"Ann"},{"name":"Bo"}]. A single object is treated as one row, and an array of arrays becomes rows directly.

With "Flatten nested objects" on, nested objects become dotted columns like address.city. Arrays are written into the cell as JSON text.

If you turn on "Protect against spreadsheet formulas", values starting with =, +, - or @ get a leading apostrophe so Excel and Sheets treat them as text instead of running them.

No. The conversion happens in your browser and your JSON is never sent to a server.

Yes. Download the .csv file and open it in Excel or Google Sheets. If your regional settings expect semicolons, choose the semicolon delimiter.
