Hi Shreyansh , Use the CSV import module from marketplace . In the Import micro flow of the module you will have an activity where you can specify the row you want to skip .
How are you importing your CSV file?
If you use the CSV Services module from the Marketplace, you can specify if the CSV file you are importing has a header or not, and this is taken into account during the import.
