How to dynamically delete Top Rows *Before a specific value in a Column1 in the below example.

Start by removing rows from the gui by putting in any number. Power query will write a line like below.

#"Removed Top Rows" = Table.Skip(Source,2)

Modify it to be the function each [Column1] <> "ID Number"

#"Removed Top Rows" = Table.Skip(Source,each [Column1] <> "ID Number")

Note that this code will work as long as all of the data in the column is text.

Hello Anonymous 

this code is created automatically by Power BI when you manully input data. I prefer to do this way to give everything the possibility to understand the solution. In future I will use the #table function to make it more clearly.

If my post works as well, I would appreciate it you marking it as solution as well or to give a like.

All the best
