As far as I can see OpenOffice, when it comes to save a file as a csv-file, encloses all strings in quote-characters.
So is there any need for an escape character?
and related to this question:
Does OpenOffice have a default escape character?
I'm also wondering if there is a way to choose the escape character when saving OpenOffice as csv. phpmyadmin was not accepting a 9,000 line 50+ column spreadsheed in .ods format and there doesn't seem to be a way to choose the escape character when saving as CSV.
So I had to save as csv, open in word, and use some find/replace tricks to change the escape character to \ (back slash). Default is to use double quotes to escape double quotes, and phpmyadmin won't accept that format.
To properly convert the file to use \ (back-slash) to escape double-quotes, you have to do this:
That will work, unless you happen to have more than one double-quote in a row in your original text fields, which would result in as many as five double-quotes in a row in the resulting .ods or .xlsx csv file (two double-quotes for each escaped double quote, plus another double quote if its at the end of the field).
