RE: Unable to import data using OOB excel import export
Hi Smita,
To avoid an Invalid format error, you can follow the below approach while working on data import/export:
If you trying to update the data of a custom entity, I would suggest you first export the data of the custom entity with whatever columns you are trying to update and after updating the data in exported excel, you can again import the same in CRM. Make sure in between export/import the data you are trying to update is not getting updated in CRM (either manually or by any other process)
And even if you try the create the records for a custom entity, then also first export any single record of that custom entity along with the required columns so that it doesn’t give you an invalid format error and then you can modify the excel and import the records that you want to create of the custom entity. (Make sure you are clearing hidden columns values i.e. Table’s Id, Row Checksum, and Modified On before importing the excel)
Hope this helps.
Thanks!
