Please read the import guidelines document attached to this article.
Those guidelines will help you understand how to produce an export file with a structure similar to the sample import people data CSV file.
If you wish to import more data, you can also use the following folder with secondary import file formats that will show you how to import associated data (events, event participation, donations, payments, etc.).
Here is the main Migration folder that contains all the files mentioned above.
If you have any questions about these migration files, please do not hesitate to contact support@
