Keep blank columns when import excel sheet

Hi, someone can help me with this:

I have to import the same sheet from differets paths, so I´ve created a function that do that and extract the third column but sometimes the sheet have the first column blank and power query imported from column B not from column A (because column A is blank). Can I keep all columns when I imported sheet?

I want to import all the columns including the empty columns (power query delete automatically) or the first 50 columns.
