I have sets of data like this on Excel 2016
Can I filter only first row by these sets of time? e.g. I want to select only first row of February 1st on 12AM and February 1st on 6AM.
Thank you for your help and attention.
As per screenshot of my answer use the following formula to K2 cell.
=IFERROR(INDEX($A$2:$A$9,MATCH(0,INDEX(COUNTIF($K$1:K1,$A$2:$A$9),0,0),0)),"")
Then use the following formula to L2 cell.
=IFERROR(INDEX($B$2:$H$9,MATCH($K2,$A$2:$A$9,0),COLUMN(A$1)),"")
Drag the formula as per your need.
