Your import templates are specific to each data source and can be exported, backed up and imported here. 

Export, Import and Delete

For individual templates

Backup and Restore 

Beginning in version 4.5, each day that Importacular is opened a backup of the templates will be made. One will be retained each day and then two a week for up to (currently) one month. As a best practice, it is still recommended that you backup all your templates on a regular basis in addition to the automatic backup.

Clone for file 

You can duplicate a template created for a specific data source for use with a file format, for example your exceptions report from an import.
