How to remove white spaces in spreadsheet

There is no in built function in excel for removing whites spaces when it appears at the end of a text or middle of a text , but you may wonder why can't we use the Trim Function. Yes, Trim () Function works when there is a white space at the beginning of a text area. But It doesn't work with with all instances.

I have also tried filtering white spaces and  do a "Find and Replace" But It replaces all white spaces within a cell , what I actually mean is when there is a single space between 2 words. This removes all the white spaces.

I finally found google sheet is a good solution to solve this problem in no time. What you have to do is

1. Sign into your Google account. 
2. Create a blank spreadsheet. 
3. Now go and copy the data areas in your excel.
4. Now Paste the copied data into newly created google sheet. 
5. All the white spaces  will have been removed. 
6. Now copy the data from google sheet into your excel.
