--- Comment #5 from ady <[email protected]> --- FWIW, Excel also complains about some kind of mismatch between the internal format and the file name extension. Was this file actually created by Excel itself? Is this file perhaps created by some other tool (which exports the data to some file, intended to be opened by Excel)? -- You are receiving this mail because: You are the assignee for the bug.
