change in a column header in an excel spreadsheet data source

[GiuseppeP]

Hello all, I have a report with some excel spreadsheets as data source. 

In one of these, a column header is changed, so before was:

column header 1, column heade 2....     and after:

column header A, column header 2.....

the data carried into the column is the same, just the header changed. What is the best way to solve expression.error the column 'column header 1' of the table wasn't found. ?

Thank you in advance

@GiuseppeP , You have to do a change in the advance editor in  power Query.

refer steps in my power bi video https://www.youtube.com/watch?v=meUxcbwujl8

Hi Amit, thanks for the help, your video tutorial is very useful. I had already tried editing the query with the advanced editor, and trying again more carefully I saw that the problem was that they had also changed the file format.
