Strange behaviour in Excel imports to Creatio

Hello Community, 

We have a client for whom we perform Excel imports of products into quotes. This import process includes a validation step where the system checks the PartNumber to verify if the product already exists. If it does, the corresponding ID is assigned to the product in the quote. If it does not exist, a new product is created with the appropriate classifications.

However, we discovered that when the PartNumber in the Excel file contains "00", Creatio is unable to process it correctly and instead associates a product with no PartNumber assigned.

Can you help us resolve this issue? Any suggestions would be appreciated!
