Sometimes in a situation like this it's useful to look at the source of the message. In the event that this is true here... This error is raised by the CSV import module here: https://github.com/omeka-s-modules/CSVImport/blob/30857ff5cbab31bb53713fc7c837b8c2c1247f6e/src/Source/AbstractSource.php#L89-L94 The checkNumberOfColumnsByRow function returning false (and triggering the error) is here: https://github.com/omeka-s-modules/CSVImport/blob/30857ff5cbab31bb53713fc7c837b8c2c1247f6e/src/Source/CsvFile.php#L126-L144 That function appears to verify two things: 1. The iterator over the CSV is not empty 2. The rows all have the same number of values as the header row had headers The iterator in question is from an SplFileObject ( https://www.php.net/manual/en/class.splfileobject.php). So either your uploaded file appears empty to the CSV reader, or some row has a number of cells different from the header row. If I were you, before I started digging into escaped values and what not, I would: 1. Make sure I had the number of headers I intended 2. Make sure my file is UTF8 encoded, and make sure I was using Unix-style line endings (a single newline character) 3. Make sure I didn't have empty lines (I notice that https://github.com/omeka-s-modules/CSVImport/blob/30857ff5cbab31bb53713fc7c837b8c2c1247f6e/src/Source/CsvFile.php#L189-L190 sets the SKIP_EMPTY flag, but not DROP_NEW_LINE), including the end of the file If you've already done these things, I apologize for being so rudimentary - but it's always good to verify the basic assumptions before you dive into more elaborate data inspection. Good luck! Ben PS: I know this stuff is frustrating - it might be worth opening an issue on that CSVImport github repository to improve the error message!
