If the file format is CSV, the short answer is you can't using Excel or Open Office. Neither of these programs retain columns widths in CSV files.. (they only display them when you have the file open)

I've been saving my works regularly while editing product data so my info isn't getting lost but the format is a mess.

Example:
I need to enter a lengthy description in v_products_description_1 so I make the entire column wider. (either manually or using the Format Cells pull-down).

After entering all of the info I save the document, upload to my site and close the workbook.

When I reopen the workbook to add more products the cells have all reverted back to their former narrow state and my data is now a jumbled mess.

So how do I keep my cells wide enough on the EasyPopulate spread sheets?
