Excel - Power Query - fill imported columns with formulas

Question

I have a Query in place, which imports some empty columns. I want those columns to be filled with some formulas, referencing other columns (from the same query).

I tried:

• "Replace Values" option, but that does not work for formulas.
• Removing the empty columns and adding them as new (non-query) columns works, but messes up the order of the columns, which needs to be the same as it is now (this is a request from the users of the file). So this was also a dead end.
• of course, I tried to enter the formula manually into the empty columns, but on refresh, the formulas were overwritten by the imported blanks (no surprise here)

Is this even possible ?

Answer 1

Power Query supports adding "Custom Columns" which are similar to adding a formula column in excel. You can add a column in any sequence you may want and also change the sequence if required.

To help with this there is also a "Create Column from Example" where you can enter a sample output in few rows and it will automatically calculate the formula for you.
