Excel sheet - Calculating 4 processors !


I appreciate your help on the below concerning the performance of an excel workbook.

I have build a new excel model of c. 5KB however all of a sudden it became 43 179 KB in size !!! When calculating it is obviously extremely slow requiring 4 processors to calculate.

How can i fix this excel model to bring it down to its original size please to improve its performance.

On each sheet in the file, press End then Home keys. The cursor should go to the bottom right of your known range of data. If it goes way beyond the expected range then it is the Used Range which is mucked up.

Manually put the cursor in the column after the known last data column and then hold Shift and Press End then Home again. This will have selected all the surplus columns, Ctrl + - will now remove those columns. Repeat for rows below the known data range.

Save the file and then try the End Home again, the cursor should now go to the bottom right of the known range.

This issue can occur if data is inserted but then later deleted or if formatting is applied to whole rows/columns rather than selected cells.

Usually if you have data filters or pivot tables on the sheets it causes the workbook to balloon in size. Remove the data filters and then save the file.

This article shows you how to improve calculation speed and how to build better Excel sheets:
Also this link tells you some tips and tricks:
For your case I recommend to turn off automatic recalculation (do it manually), turn off add-ons you do not need, save the file as binary - xlsb and check your calculations against best practises in articles above.

please confirm if you are using any of of the below volatile functions in your model

AREAS()   INDEX()   OFFSET()   CELL()   INDIRECT()   ROWS()   COLUMNS()   NOW()   TODAY()   RAND()

i am using TODAY() formula in my model.

Are there any implications with this please?
how many times TODAY() function is used in your model?

TODAY() function is super voilatile and i suspect this is the culprit that made your spreadsheet very slow.

Also, take a look at Conditional Formatting. If there are multiple occurrences of the same rule for different cells (rather than one rule for a range) these can take time to recalculate; particularly if they use volatile functions like ProfJJ mentions.
