@Ani25

you can use the "Write cell " activity for writing the formula
have a look in this thread->

Please suggest me some sample for my datatable

you can go with vba and just do it manually and record and use

go to excel > developer > record macro> do your manual action > stop recording > macros> macro name> edit code

copy and paste the code in notpad and use invoke vba activity and mention code filepath and macro name

Hi,

You can use auto fill range
Take a write cell and write the formula . eg column C2
then take auto fill range and give the values as in image reference
auto fill range works in excel application scope only
