Hi,
If you have prepared CSV files, then use CSV Importer available on the Freshworks marketplace. Just ensure you’ve downloaded a sample CSV file to check if you’ve filled in all columns correctly. Note that companies have different names on Freshservice, mainly departments.
Depending on your current solution, you can check if there’s any available integration with Freshservice too. This way, you can use the data from your current platform on Freshservice.
A third option is to migrate companies from your current platform to Freshervice with an automated tool. For more details, read on this article.
