You can convert .xls to .csv format and then do simple text search (and replace) in text file.

    and then I will again convert it into xls, don't you think it will be too much time consuming??

      Yes, I agree. That's just one of solutions and I check Excel modules on CPAN, but until now have found only modules like Excel::Writer for creation of Excel worksheets and without simple 'find and replace' function.

      I guess the best approach for you would be to use Win32::OLE module, example with using 'find' function is presented here Re: Win32::OLE Excel search and replace commas (adapting it to find & replace should not be hard).

[Corion]: But maybe there is some other Unicode string that will be true but have a zero width
[hippo]: For explanation, I've seen this construct in someone else's code (no names, no pack drill) and couldn't think of a situation to trigger it.
[Corion]: You'll have to look somewhere esoteric for that. Maybe some tied variable or special dualvar can also trigger that. But it's certainly not a common occurrence
[Corion]: And on 5.20, the following also outputs no find:perl -wle 'for my $x ("\x{2000}".."\ x{1fffff}") { if( $x && ! length $x ) { warn qq(<$x>); warn length $x; die } }'
[Corion]: (this time on Unix)
[hippo]: Understood. I'll have to go through the code and see if it's doing anything fancy with ties, dual-vars or non-scalars. In the end, it's probably a bug though.
[Corion]: Aaah - you should be able to do this with overload, but I would hit somebody really hard if they constructed objects that are true but the empty string, and you not knowing about the domain knowledge where this makes sense
