Google Sheet Formula is much heavier to load

Question

Using below formula to count the leaves between the dates. That formula sometimes give result and sometime sheet keep gives an error of reloading the sheet.

I think this formula is much heavier to make calculation.

I have attached an sheet where formula works.

looking for an easier way or formula to make calculation that below formula does. Your help will be appreciated.

=ArrayFormula(IFERROR(1/(1/(IF(B3:B="",,LEN(SUBSTITUTE(TRIM(TRANSPOSE(QUERY(TRANSPOSE(IF(
 IFERROR(VLOOKUP(ROW(Jan!A3:A), {ROW(Jan!A3:A), Jan!C3:AG, Feb!C3:AE, Mar!C3:AG, Apr!C3:AF, May!C3:AG, Jun!C3:AF, Jul!C3:AG, Aug!C3:AG, Sep!C3:AF, Oct!C3:AG, Nov!C3:AF, Dec!C3:AG}, 
 IF(1=SPLIT(REPT("01", DATE(YEAR(E3:E), MONTH(E3:E)+6, DAY(E3:E))-("01/01/2020"-1)), 0), COLUMN(B:AAA), )*1, 0))<>"C", 
 IFERROR(VLOOKUP(ROW(Jan!A3:A), {ROW(Jan!A3:A), Jan!C3:AG, Feb!C3:AE, Mar!C3:AG, Apr!C3:AF, May!C3:AG, Jun!C3:AF, Jul!C3:AG, Aug!C3:AG, Sep!C3:AF, Oct!C3:AG, Nov!C3:AF, Dec!C3:AG}, 
 IF(1=SPLIT(REPT("01", DATE(YEAR(E3:E), MONTH(E3:E)+6, DAY(E3:E))-("01/01/2020"-1)), 0), COLUMN(B:AAA), )*1, 0)), )),,9^9))), " ", )))))))

error.

Answer 1

Upon checking, it seems there is nothing wrong with your formula. And I see even worse formula than this that are still functioning correctly on large data sets so I did check the data itself.

Problem :

• The days in the month sheets you are comparing to your Sheet1 columns E and G are just integers/numbers resulting COUNTIFS calls having false conditions.

Fix :

• Convert the integer/number days in the first rows of all sheets to date format.

I just converted all day cells in all sheets into dates and show them as just day in custom date format (to show the same format of your sheets). By doing this, you make COUNTIFS function properly and return the proper number of leaves.

Showing only in cells as days but containing date values

Expected result is being matched

Although, you mistakenly counted for Employee5 as 1 instead of 4
