Hi @BLabat83
Action Find or Replace in datatable will find the value in datatable everywhere or within a particular column and will return a datatable which looks like below

Here Row column will contain the row index where it is located and column represent in which column of that row the value is located. In my case, I have used below datatable

I am trying to find out the position of A1 in datatable which is at row index 0. So using the Find or Replace in datatable, you will get an output like above in datatable format where for each row you will get its row index in row column and column index in Column column, so using row index you can get which row value resides and based on which you can retrive the other column name 🙂
In my case, i need to retrive B column value where A1 row value is there, Try this way
First convert the output from datatable macthes to number like below

Now use the below expression to get the B column value
