I'm trying to read an Excel file (Office 2003). There is an Excel file that needs to be uploaded and its contents parsed.
Via Google, I can only find answers to these related (and insufficient topics): generating Excel files, reading Excel XML files, reading Excel CSV files, or incomplete abandoned projects. I own Office 2003 so if I need any files from there, they are available. It's installed on my box but isn't and can't be installed on my shared host.
You have 2 choices as far as I know:
PHPExcel uses Spreadsheet_Excel_Reader for the Office 2003 format.
Update: I once had to read some Excel files but I used the Office 2003 XML format in order to read them and told the people that were using the application to save and upload only that type of Excel file.
