Not a valid currency error

Not a valid currency error

My client reports:


I continue to experience errors when attempting to  import currency from my excel files. The issue began about 4 weeks ago. Previously, for the past year, I never had an issue. I have not change anything in the excel files we import from. Seems Zoho has changed something. 

I am having to edit 9 excel files each week so the Zoho application will accept the import. Then I have to change each excel file back to its original format so I can email to customers.

Wow, what a pain!
