Loading csv file trying to replace double quotes

Question

Hi, I am trying to load a csv file with a field with double qoutes that I want to replace the double qoutes to one. The CSV file I will enter
"TEST,2345" in a field and when it loads its as ""TEST,2345""
So I got this code to handle it.
Pattern quotesRegex = Pattern.compile("\"\"");
          Matcher m = fieldRegex.matcher(line);
          while (m.find()) {
               String field;
               if (m.group(1) != null) {
                    // If a quoted string was matched replace escaped double quote,
                    // "" with "
                    field = quotesRegex.matcher(m.group(1)).replaceAll("\"");
else {
                    field = m.group(2);
               fields.add(field.trim());
I want to change a line like this
D,,""TEST,2345"",46,,
to
D,,"TEST,2345",46,,
but afterwards nothing has changed the record looks as below
D,,""TEST,2345"",46,,
Whats wrong with this?
thanks

Answer 1

I simply created a simple csv file with one field that I entered a double qoute of "TEST,2345"
Later when reading in the file(using the code I pasted in) I can inspect it and its """TEST,2345"""
The relaceAll doesnt seem to change anything(nor did my code). So I was stumped. thanks
