Exporting requests allows you to import them into other bases. None of your workspace or base data will be exported, just the details of the saved request.
Export requests as JSON file
On the home screen, hover over the requests you want to export and click the checkbox.
Click "Download file".
Be careful if there are API secrets or other sensitive data in the requests you export. You probably want to replace them with variables first, so that only the variable names are exported, not the actual values.
