The way that I understand it is that if a comma is enclosed in quotes, (as is the case with "OOMA, INC") then the comma should be ignored. I'm not sure if Moneydance's built-in importer ever handled this situation properly though.
Personally, I use a free, third-party CSV Importer designed specifically for Moneydance that properly ignores the comma between OOMA & INC. I was able to successfully import your example transaction using the CSV Importer.
Per your screenshot, it looks as though you've created a custom reader named MyCSV.
I'll give you the settings that I used to import your example transaction. I'm in a Windows environment so my screenshots may appear slightly different than yours.
Download a CSV file from your bank to your 'Downloads' folder.
From the Moneydance Menu bar, go to Extensions > Import File.
When the main screen of the CSV Importer opens, click the 'Maintain Custom File Readers' button.
In the resulting window, set up the custom reader per my screenshot. (Paul_CustomReader.jpg)
Although you've already named your custom reader 'MyCSV', I'll include the following paragraph for informational purposes...
For the 'Reader Name' you can, of course, name the reader whatever is informative to you. I chose 'Paul'. Enter the desired name and click the 'Add' button. The name that you just entered should now be listed in the 'List of Readers' section.
Leave the 'Filename Matcher' field as is. .*.(csv|CSV)
Continue by making sure to enter the proper Date Format: MM/dd/yyyy
Number of Header Lines: 0
(your example transaction had no header but make sure to check if your bank's CSV file does or does not and make the appropriate entry)
Number of Footer Lines: 0 (again, check your bank's CSV)
CSV Field Separator: ,
File Encoding: UTF-8
Decimal Sign: .
Set Fields 1 ~ 5 as indicated in the screenshot.
When you've completed setting up the custom reader, click 'Save' and 'Done'.
(Back at the main screen of the CSV Importer)
Make sure that the proper File Reader is selected (for when you have more than one Custom Reader)
You should then be able to click the 'Find Import File(s) for this Reader' button. If clicking that button does not populate the 'File' field then click the [...] button to navigate to your CSV file.
Make sure that the proper Account is selected to import the file into.
For the 'Import Transaction As' option, I generally use the 'Online' option. You can experiment with that and see which option serves you best.
Look things over, make sure everything is correct.
Click, the 'Preview Import' button.
A preview window will open. Provided there are no 'red' or 'yellow' flagged txns listed in the preview, you can go ahead and click the 'Process' button.
The first time that you run the CSV Importer, there may be some informational message that pops up. I forget exactly what it reads but you should look that over. You'll then receive a message indicating the number of imported items as well as other information relevant to the imported txn(s).
