If you have ever worked with drop down lists in Sage ACT, you know that you can import items to populate the list. The list has to be a text file with the items one per line, enclosed in double quotes.
I like to use Excel to key in the data, sort it, remove duplicates, etc. Then save the file as a text file. However, it doesn't put in the double quotes.
Here's a formula you can insert in a column next to the data. Assume the text items are in the A Column.
=concatenate(char(34),a1,char(34))
Put the formula in the B column and copy down to the last line of text in the A Column. Copy the B column and paste special values into the A column. Delete the B column.
At this point, because Excel still does weird things when I try to save it as text, I copy the A Column and paste it into a notepad, and save it as txt. Now I have a nice clean list to import into my dropdowns.
