--- Comment #13 from Mike Kaganski <mikekagan...@hotmail.com> --- FTR: Typing file.csv in the MS Excel's Save As dialog (note how it's the *same* dialog that *actually allows* to save as CSV, unlike what comment 9 did!) having XLSX file type selected, I get a 'file.csv.xlsx' without warning. If I use double quotes to force the exact filename, and type "file.csv", I also got no warning, but I still get the XLSX with "wrong" extension. If I use the same procedure in Excel's Export dialog, I have similar results: no warnings, always get the file type selected in relevant dropdown, but when I use quoted filename, I get "csv" silently replaced with "pdf". In any case, the other major spreadsheet software vendor doesn't get convinced by Jonny Grant's "If I type "Untitled 1.csv" in the box, I expect it to save as CSV". -- You are receiving this mail because: You are the assignee for the bug.
