I want to change my data, in excel, from the form, e.g (100) to (100/100)
for another software to recognize the data. The data is huge and wish I could
do it automatically .
I have tried the 'Concatenate' formula but it returns the product of the
formula instead of the form I want it. Any help please?

=concatenate A1,/A1 meant to change (100) to (100/100) returns (1)
