* Fix for 3 Issues Involving ReadXlsx and NamedRange Issues #1686 and #1723, which provide sample spreadsheets, are probably solved by this ticket. Issue #1730 is also probably solved, but I have no way to verify. There are two problems with how PhpSpreadsheet is handling things now. Although the first problem is much less severe, and isn't really a factor in the issues named above, it is helpful to get it out of the way first. If you define a named range in Excel, and then delete the sheet where the range exists, Excel saves the range as #REF!. If there is a cell which references the range, it will similarly have the value #REF! when you open the Excel file. Currently, PhpSpreadsheet discards the #REF! definition, so a cell which references the range will appear as #NAME? rather than #REF!. This PR changes the behavior so that PhpSpreadsheet retains the #REF! definition, and cells which reference it will appear as #REF!. The second problem is the more severe, and is, I believe, responsible for the 3 issues identified above. If you define a named range and the sheet on which the range is defined does not exist at the time, Excel will save the range as something like: '[1]Unknown Sheet'!$A$1 If a cell references such a range, Excel will again display #REF!. PhpSpreadsheet currently throws an Exception when it encounters such a definition while reading the file. This PR changes the behavior so that PhpSpreadsheet saves the definition as #REF!, and cells which reference it will behave similarly. For the record, I will note that Excel does not magically recalculate when a missing sheet is subsequently added, despite the fact that the reference might now become resolvable. PhpSpreadsheet behaves likewise. * Remove Dead Code in Test Identified it after push but before merge.

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 master branch.
Do you need to migrate? There is an automated tool for that.
