Removing the duplicate strtoupper call has a meaningful impact on performance since this method is called at least once per cell. `Worksheet::getCells` currently calls `strtoupper` twice. `strtoupper` is kind of expensive and this method is called at least once for every cell in the spreadsheet. By removing the unnecessary second call the runtime decreases by 18% when importing a ~100K cell spreadsheet. Closes #825 |

PHPExcel vs PhpSpreadsheet ?
PhpSpreadsheet is the next version of PHPExcel. It breaks compatibility to dramatically improve the code base quality (namespaces, PSR compliance, use of latest PHP language features, etc.).
Because all efforts have shifted to PhpSpreadsheet, PHPExcel will no longer be maintained. All contributions for PHPExcel, patches and new features, should target PhpSpreadsheet develop branch.
