Using @ and # in the .csv and .xlsx files for bulk scheduling tweets

Using @ and # in the .csv and .xlsx files for bulk scheduling tweets

Hello! I am currently trying to use the bulk scheduler tool for my twitter account but when I try to tag people using @ or add on trending hashtags (#) the excel workbook won't let me

Is this an issue with excel or zoho

is there a way around this issue 

Thankyou :)
