A regular question we get at Zapier is: Can Zapier import/export my data from App A to App B?
Unfortunately, Zapier is not designed to mass import/export your data between two apps. We can only trigger from new data added to App A and send it over to App B only after creating and turning on a Zap.
While Zapier can't natively import/export existing data from one app to another, we do have methods one can employ to get around this limitation.
If you are able to get your data into a spreadsheet format like an Excel or CSV file, you can use Google Sheets as an intermediary app in creating a Zap that mimics an import/export function of data from one app to another.
