Hi Max & list,
We get a version of this error a lot when reading Excel or CSV files into
the Dataverse data repository (which has a library that parses tabular data
into .tsv/.tab files) and in 9 out of 10 cases the problem is a multi-line
cell. Those are valid CSV as per RFC4180 (with the line break in double
quotes) and work with tools like Excel/LO, but many parsing libraries can't
handle them and if the linebreak creates a new row, you get a misalignment.
Just guessing, obviously, but worth looking out for.
