A dataset contains ten survey answers, but a text editor shows more than ten lines. Some answers may include line breaks inside a quoted field, so visible lines and data records are not necessarily the same count.
Read the quoting convention
RFC 4180’s CSV description allows fields containing line breaks to be enclosed in double quotes. It also describes doubled quote characters inside quoted fields. Real exports vary, so inspect the producer’s format documentation and parser settings rather than repairing the file by deleting line breaks.
Check a small parsed example
Use a suitable CSV reader to inspect the number of records and fields. Compare one multiline answer with the original source where available. An editor’s line counter is useful for navigating text but is not a reliable record counter for every CSV file.
Keep the original export intact while investigating. A successful import should preserve the answer’s text as well as the table shape. If you normalise whitespace for analysis, record that transformation explicitly so a later reader can distinguish source formatting from your cleaned version.
