Abstract

A method and system for loading files into a spreadsheet application program (SAP) operating on a computer system, using an escalating load sequence. The SAP determines if a normal load mode failed while attempting to load the files. In response to determining that the normal load mode failed, the SAP escalates the load sequence to a safe load mode, where a plurality of checks are performed and the files are repaired. The SAP also determines if the safe load mode was successful in repairing and loading the files. If the SAP determines that the safe load mode was unsuccessful, the SAP escalates the load sequence to a data recovery mode, where the spreadsheet application program attempts to extract formulas and values from the file.
