[In reply to] Can't Post FishMonger, Your solution appears to be about the same as mine but with all the error detection and recovery that Laurent specified. Good job. It appears that the discrepancy in the quoting has been the underlying problem. I hope so! Good Luck, Bill

[In reply to] Can't Post When I open the file in Excel I don't see the extra quotation marks, but they appear when I open it in Notepad. So is it most likely that perl is viewing it with extra quotation marks?

[In reply to] Can't Post Since this is a plain text file, why are you opening it with Excel instead of a text editor? That doesn't make any sense. If the quotes aren't showing up in Excel, then you used the wrong import settings. Perl is reading the file correctly, but Excel isn't because you used the wrong import settings.

I just downloaded Notepad++ and used that... script worked perfectly. I'd like to thank you all for your help, and I'd like to apologise for the trivial nature of the problem! Many thanks.

[In reply to] Can't Post Good to see that you are finally where you wanted to be. One lesson to be drawn: don't open a text file with Excel (or Word or other word processors, for that matter) if you are planning to save it and hope to process it afterwards. MS Office applications are likely to add all kinds of characters (sometimes invisible) or also remove some others which will often ruin subsequent processing, be it in Perl or with any other language. Text editors (as opposed to word processors) such Notepad++ are good at that because they preserve the text. Uner Windows, you could also use the Crimson Editor, Ultra Edit (shareware), jEdit, etc.
