Posted on 2013-11-05

I have timesheet data collected from a fingerprint reader and have organized it in a pivot table on sheet 2 of the attached file.

I would like to get formulas in columns BA to BE for

Total hours worked
No of days counted
Average hours worked on each day
No of days worked less than 8 hours

whenever a time in as well as a time out is recorded.

In addition I would like to have a count of days present whenever there is at least one of time in and time out recorded.

ssaqibh,

You time log data doesn't seem to be completed. Most people don't have both In and Out time. That creates a big problem in calculating the time.

There was no "Out" column that corresponded to the "In" of column AZ, so I inserted an extra column before your requested formulas.

I used offset ranges along with a test for even/odd column numbers to test for times being reported for both "In" and "Out". This forced me into a SUMPRODUCT formula.

Total hours worked
=SUMPRODUCT(\$E6:\$BA6*ISODD(COLUMN(\$E6:\$BA6))*(\$D6:\$AZ6<>"")*(\$E6:\$BA6<>""))-SUMPRODUCT(\$D6:\$AZ6*ISEVEN(COLUMN(\$D6:\$AZ6))*(\$D6:\$AZ6<>"")*(\$E6:\$BA6<>""))

Number of days worked
=SUMPRODUCT((\$D6:\$AZ6<>"")*(\$E6:\$BA6<>"")*ISEVEN(COLUMN(\$D6:\$AZ6)))

Average number of hours worked
=BB6/BC6

Number of days worked less than 8 hours
=SUMPRODUCT((\$D6:\$AZ6<>"")*(\$E6:\$BA6<>"")*((\$E6:\$BA6-\$D6:\$AZ6)<8/24))

Number of days with time reported
=COLUMNS(\$D6:\$BA6)/2-SUMPRODUCT((\$D6:\$AZ6="")*(\$E6:\$BA6="")*ISEVEN(COLUMN(\$D6:\$AZ6)))DUCT((\$D6:\$AZ6<>"")*(\$E6:\$BA6<>"")*((\$E6:\$BA6-\$D6:\$AZ6)<8/24))/BC6

My formula for number of days worked less than 8 hours was wrong. It needed to include a test for even column number.
=SUMPRODUCT((\$D6:\$AZ6<>"")*(\$E6:\$BA6<>"")*ISEVEN(COLUMN(\$D6:\$AZ6))*((\$E6:\$BA6-\$D6:\$AZ6)<8/24))
