Import of hotel properties - too many field to be uploaded successfully

[Khoi - d2o]

Hi all! I've had some problem importing data that has alot of fields in our CRM. I tried to upload 10 fields but it did not successfully upload, i therefor had to reduce to import only 6 of the fields while remaining fields I had to fill in manually which is quite alot considering we have imported 500 properties with fields that need to be filled.

Is there anyway to do a second import of the remaining 4 fields for the same properties? I tried this but everytime i did this the import got overrided. meaning I successfully imported the 4 fields while the previous 6 fields now dissappeared (went empty). There should be a way to improt remaning fields without loosing the previous ones right?

Looking forward to your reply!

Hello
Map fields and columns, you want to update and one unique field (name or some number), and next to that unique field check Update by box
