Dear CCI Members,

Sub: TNVAT Offline Software

I installed the TNVAT offline software tool.

While uploading the Annexures I am given the following options:
1. Click Here To convert Excel to .xml or    
2.Click Here To Download Excel Template
 
While I upload the .xls file I get an error like " Upload Failed. Please upload Again"
 
Why do I get such error message?
 
I even tried downloading the excel template, it is a .part file & is not working.

Kindly help me, filing VAT returns using the offline tool.
