Hi Paul,
Thanks for your reply. It didn't seem to have worked. Steps followed as below:

1. In a word file just do ctl+F and find [^033-^043^045^047^058-^064^091-^096^123-^255][ ]{1,}
2. 'replace all' with nothing

3. again ctlr+F and find [ ]{1,}[^033-^043^045^047^058-^064^091-^096^123-^255]
4. 'replace all' with nothing

This did not work!

But alternatively what i have found is to run a macro to do the required stuff.
Thanks for your response anyways.
