First of all I bought my first mac in Oct 2010. I have an online biz where I use xls a lot for my inventory downloads from my suppliers. For this issue I have searched this forum, searched the open office forum and googled my question but haven't found the answer. As a PC user, I would go into the control panel and change the folder options to view txt files as xls. This was just a one time situation as I downloaded an inventory from my supplier site, text delimited but after I would unzip that file, since I changed the VIEW to xls, that file would open up as an excel spreadsheet. I would then go back to the PC Control Panel and change the view for txt files back to text. Since using my mac, I found that open office worked better for my spreadsheets instead of the Numbers for one key process I use a lot....right click cell, and paste special, paste link.....I never found an easy way to do that in Numbers so I use OpenOffice. Is there a way I can change the view BEFORE downloading this txt file, either in Numbers or OpenOffice, so that once the file is unzipped (Zipeg), it will open up in a spreadsheet? If not, is there a way I can convert that downloaded txt file into a xls file either in Numbers or OpenOffice? Thanks in advance for any help on this issue. I'll continue to read and look until then.
