You could but you shouldn’t.
1. Only Zendesk customer support can enable JSON imports
It is not currently possible to import a JSON export to recreate a Zendesk file. As a result, even if you’re regularly exporting your files as JSON files, you will have to manually recreate them if you run into a problem.
2. JSON is hard to use
The JSON is a highly technical format meant for machines to interpret and use. As a result, it isn’t as easy to read as an Excel or CSV file. Take a look at what information about a Zendesk card will look like in JSON format:
For a Zendesk user looking to quickly recover from a mistake, parsing through JSON notation can be quite cumbersome.
3. You have to remember to regularly export new JSON files
If you make the mistake of relying on JSON files as your backup, you will have to remember to update those files on a consistent basis. In some cases, even a week-old export might be too outdated to be used to recover after a problem. This is especially true for Zendesk users who make important changes to their files daily.
You should think twice before deciding that exports are a sufficient backup solution. Use Rewind to back up Zendesk and ensure that your information is fully protected and easily recoverable.
