  <p>I need to extract into Power BI only the fields in the middle, excluding the first 3 lines and last 4 lines. I was thinking in using a Windows Command line to cut the unwanted lines and import using &quot;Folder&quot; option in Power BI. Also... the date changes according to TXT file, but not the variable names.</p>
  <p>Any suggestion to cut the unwanted lines? Should I take different approach?</p>
