Absolutely! In fact, we strongly encourage it especially if this is your first import. Please feel free to start a chat, where you can send your file to Support for troubleshooting, and we can walk through any necessary edits to the file prior to the import. We can also walk you through the actual import process step-by-step and help ensure all import data maps correctly to your Bloomerang fields. We ask that you first thoroughly review our documentation on imports here so that you understand the overall process.
