I have a Datatable from an excel file
I have in there something like 20 columns and more rows than I can count.
I took all the data from the DT I got and did some stuff (insert the data to a webpage etc.)
after that, I want to insert new data to my excel file (in a new file).
I have 7 new columns that I need to append the existing ones… (I know the names of the new columns).
and of course, insert the data into them (in the correct row).
for example, this is the input I get
and this is the output that I need to add
if u will notice after the FCW header there is 7 new columns (it’s in Hebrew)
please help me!!!
