Join David D. Levine for an in-depth discussion in this video Parsing Excel CSV files: Commas and new lines, part of AWK Essential Training.
…The previous move discussed the basics of…parsing Microsoft Excel CSV files using AWK, including…dealing with the MS-DOS line endings, quoted…cell values, and quotes within quoted cell values.…This movie continues Excel CSV parsing, including the more…difficult problems of commas and new lines within cell values.…The second case in which Excel will surround a…field with quotes is if it contains a comma.…If this occurs, there is no easy way for AWK…to tell which commas in the CSV file actually delimit fields.…
If you Excel data contains commas, my recommendation is to open the CSV file in…Excel or the original Excel file and resave it in tab delimited text format.…So we'll do that.…Yes, we really meant it.…Once you have done that, all we need to…do is change the field specifier from a comment to…a tab, and work with the .TXT file we just…created instead of the CSV file we were starting with.…Other than that, you can use the exact same AWK program…we developed in the previous lesson to deal with any quotes.…
