Creating columns from a comma

Question

I have a CSV file that opens with all the text in column A. I need to create a column at every comma. How can I do this?

Answer 1

Chris, as your profile says you're in Pennsylvania, it's unlikely that you machine is set to use the comma as the decimal separator.
To check enter these into two separate cells:
123.45
123,45
If the results are 123.45 and 12,345 then the period is your decimal separator and the comma your thousands separator, which is the standard setting for a US (English) machine. Numbers should recognize a filename.csv file formatted as you've described and should OPEN that file with the data correctly placed on a single table.
Numbers will not, however, INSERT that file correctly into an existing table, nor will it recognize and correctly OPEN or INSERT a CSV file that does not include the .csv extension to the filename.
If you want to place the data into an existing table, here's a procedure:
Open the file using Text Edit or Pages.
Delete the " at the beginning of the data and the one at the end of the data.
Do two passes of Find/Change
1. Find: "," (enter all three characters— quotation mark comma quotation mark)
    Change: tab (in Pages press option-tab to enter a tab character)
    Change All.
2. Find: "return" (in Pages press option-return to enter a return character)
    Change: return
Change All.
Select All and Copy.
In Numbers, click on the top left cell of the array where the data is to be placed, then Paste.
