Bug Help with removal of blank spaces in a file

Hello..
I have a text file. I want to remove all the blank spaces(except tab) from the file..

I tried using sed command as shown below
Code:
sed 's/ //g' file1

But the problem with the above command is that it also eliminates 'tab' which is between the columns..


For example if the contents of the file are
Code:
1<tab>a,<space> b,c<tab>        c,<space>d


Then if I use the above command, I get the following output
Code:
1<tab>a,b,c<space>c,d

Observe that a tab between the 2nd and the 3rd column has been converted to space!! Smilie
I really don't want to remove tabs!

Can anyone help me out??
Thanks in advance.
