I wrote a program that pulls data from a database and puts it into a text file. The users then use Excel to view the data that was retrieved, however, I am having a problem with some of the columns like the zip code where excel will automatically take any leading zero's off and right justify it. Is there a way to disable this (or something I can put in the text file) without having the user go in and change the format each time they open a file in excel? Also, some of the longer numbers are automatically displayed in scientific notation. I would like them to all be left justified and show all the number (or letters that is in the text file). Any help would be greatly appreciated. Thanks.
