Created attachment 141103 [details]
example csv

The attached is a csv file generated from an old dos app. It is CSV but it imports into LibreOffice as one line, the newlines are not being recognised.

Note, this file can be imported successfully by Excel. After saving it as csv in Excel, it works. Excel strips out all the 00 byte values, perhaps they are confusing LibreOffice?

excel's rewrite of the CSV file, which now imports in LO

This attachment is the csv generated after importing the original file in Excel and saving it again. The quoting of text fields has changed, but it is the 00 bytes which cause the problem

00 bytes replaced

I used a hexeditor to replace the 00 bytes with 0x20
Now it imports into LO. So the 00 bytes are definitely the problem.

Comment 6 Roman Kuznetsov 2021-02-22 17:55:02 UTC
LO Calc opens that example CSV with three rows if you select ' instead " in "String delimiter" drop-down list in "Text Import" dialog.

I think we can close it as WFM.
