Hi all,

I'm facing an issue while importing the GSTR1_Excel_Workbook_Template_V2.1 Excel file into the GST Offline Tool Version V3.2.2.

When I try to import the file, I receive the following error:

Error Message:

Following documents contain invalid inputs:
Possible Reasons:
• Invalid date format provided for the inputs
• Did not provide values for required fields
• Given 0 value for invoice number
• Given 0 value for gross advance received (Gross Advance Received can be saved as 0 only in tool)
• Given 0 value for taxable value (Taxable value can be saved as 0 only in tool)
• Given negative value for invoice/note value or taxable value or tax amounts
• The HSN code mentioned is not present in GST HSN master
Please check for mandatory fields, validations, date formats (dd-mmm-yyyy) and invoice/note number

Error Rows:

  • B2B, SEZ, DE - Row: 5

  • EXP - Row: 5, 6, 7, 8

  • EXPA - Row: 5

I have checked all the data and found correct. I think it might be issue with date format?! The date format in the Excel sheet is dd-mmm-yy, but I am unable to change it to dd-mmm-yyyy because the date fields are locked in the template.

Has anyone else encountered this issue? Is this the issue with date? Is there a workaround to fix the date format, or a way to unlock and correct the fields?

Would really appreciate any guidance from the experts here.

Thanks in advance!
