Import data file has error

jirikadlec2[CodePlex]
There is a problem in the upload data file page (import_data_file.php). My data file is formatted exactly as required, but I get an error: quotinvalid column headersquot. I created it in Excel by quotSave as csvquot. Please see the attached file.

Start with import_data_file.php and reproduce the upload using the attached CSV file, checking why a file saved from Excel is reported as having invalid column headers. Done means the provided, correctly formatted data file is accepted or the issue clearly identifies the exact header mismatch causing the error.
