I have a php page that outputs to excel.
It pretty much is a dump of a form.
When I print to the screen, without the following lines
header('Content-Disposition: attachment; filename="' . date("F_j_Y_g_i_a") . '.csv"');
Everything is as it should be.
When I add those lines, if I have the number 012345678901234567890, excel converts
it to 1.23457E+19 as soon as I open it. If I try to convert it to a number, once in excel,
it drops some numbers, it goes to 12345678901234500000.00
How do I prevent excel from formatting this string.
I don't specify any sort of number at all, I just print out with tabs and "\n"
