Use our free tool to convert from JSON (.json) to CSV

*.json* is a common file format that is often used to share data between different systems and programs.

However sometimes it is preferable to work with CSV files as they can be read by more software, including spreadsheets such as Microsoft Excel or Google Sheets.

Our converter works entirely in your browser, so none of your data will be sent to our servers.

Use our free tool to convert from SPSS (.sav) to CSV

*.sav* is the file format used by SPSS. It is a common way of storing large survey results. However it is a not a standard format and can't be read by a lot of software.

Our online tool will convert .sav files into CSV files in seconds. CSV is a simple open format that can be read by many different software packages, including Google Sheets and Microsoft Excel.

To convert your file, click the button above and select a ".sav" or ".spss" file. We will then convert it to a CSV file which you can analyse in AddMaple or download to your computer. 

How does AddMaple convert your SPSS files?

Your file will be securely sent to our servers to be converted instantly. Please note, your file is not saved on our servers, it is converted and sent back to your browser.
