excel – csv recognized as sylk

Posted by: admin May 14, 2020 Leave a comment


I’ve got a downloaded tab-delimiter csv through a PHP script.

If I open it with Excel, it is recognized as a sylk file, and I can’t open it (excel can’t read it, so in the end I’ve got a blank sheet); but if I use openoffice I can read it correctly.

I’ve searched some “strange” char (ex. I’ve searched a different HEX tab decoding) but nothing seems strange.

Is it possible to “convert” and have it openable through Excel?

or start with this string; if it is, change it before trying to open it with Excel
