Tip 2: Save the Excel file in .xlsb File Format

Do not want to edit anything in the spreadsheet (very similar to above case) only change is the file format in which you save the spreadsheet.

xlsb is Binary File Format, which will save your excel file in binary mode. Compressing/Reducing your Excel File Size to a great extent and the added advantage is, it can accommodate Macros unlike xlsx file format, and works way faster than any other excel file format.

Tip 3. Remove Unused Cells

Most people ignore this and burn their hand with huge file size and fatty lags.

What are these unused cells, basically there is a difference between ‘Actual Used Range’ and ‘Default Used Range’.

For example in the below given images, Actual data starts from cell ‘A1′ and lasts at cell ‘I14′ that is all we are interested in.

But when I press CTRL+END key excel shows cell ‘I65526′ as the last used cell in my sheet. Surprising!! Yes it happens very often. The more beyond ‘Default Last Cell’ would be from ‘Actual Last Cell’, the more unnecessary size of excel workbook would it be having.

Do not worry just select the unused cells and delete the entire rows and save your file and see the change in file size.

Tip 4. Remove Cell Formatting

We do lot of formatting to the spreadsheet and we leave it there even though they are not adding any value to the main data. Removing formatting will save you more on file size, increase the spreadsheet performance and makes it look better or simple.

Follow below steps to remove formatting

Select the range which you do not need any kind of formatting.
Home Tab > Editing Group > Clear > Clear Formats

Best option if the spreadsheet contains lots of text.

Tip 5. Save the File in Right Version

Save your Excel file in the version that you are using. Saving your excel file in lower version will just make your file size increase. For example; if you are using Excel 2007 and above version, try to save your files in .xlsx, xlsm, .xlsb file formats unless otherwise the end user has the lower version.
