Does anyone know how to upload a CSV to Netsuite that contains leading 0's in the CSV data?

What field type are you wanting to upload into?

ah, it's a custom field. 7-12 digits

is it Free Form Text?

yes

in that case the issue won't be NetSuite, it'll be Excel trying to be "smart"

ahh, okay. i'll go for solving that

You can put leading 0's as much as you want - as long as the data is in the CSV. If you use Excel however, you have to have that column formatted as Text, not General

we'll keep trying - excel seems to be fighting that solution. thank you!

If you have the data in the CSV originally, and you want to modify it in Excel - use the Excel Data Import Wizard to ensure the CSV data is preserved, as opposed to just opening it up as a CSV
