Hello Don/Aia,

Actually I want to use the Regex in a VBA application under Windows, but I'm testing the Regex in an online regex tester (Regex Tester).

The thing is that is a CSV file with comma as field delimiter and since could be commas inside fields, it's used the double quotes as text qualifier in order to avoid confusion between commas that separate fields and commas that are inside the fields. So, each field could contain any text (alphanumeric, spaces, symbols etc) and I want to match only those that have at least one comma. If it is too much complicated then I'd like to match only fields that are surrounded by double quotes.

each line of CSV could be like:
any text,"any text","any, text","any,text",,,2,45,any text

Where any text could a combination of alphanumeric, spaces, symbols etc. Because of that I was trying to match any character doing [.]+,[.]+ but t doesn't work.

Double quotes always appear in pairs since surround the fields (some of them) and there is no escaping character.

Hope make sense.

Regards
