SergeiBaklan it shows 1218272 because it was active line, my curser was on this line. I was confirming if power query reads 1st 1218272 lines or randomly reads lines. Turns out it randomly reads rows of data as line 1218272 in notepad++ and 1218272 in powerquery data load to sheet are different (I splitted the records at 1 million rows so these 1218272 rows were loaded into 2 sheets within same workbook).
