Export the result as a simple text file, or just copy it to your clipboard.

You also have "copy" button in the menu, to quickly copy the entire text to your clipboard.

A backup will be created automatically on every paste, so you do not loose you progress.
You can create, delete, rename, restore backups by yourself in the Backups section.
This will allow you to easy switch between 2 (or more) JSONs.

Thank you for your rating. The app has a "better" saving for files, it's just called "Export". Its the second button from top in the left pull menu. There is even a new (better) version out - check it out and reevaluate the app :)
