CALCULATION_REGEXP_CELLREF is not sufficiently robust. It treats some perfectly legal defined names, e.g. A1A, as cell refs. When the Xlsx Writer tries to save a worksheet which uses such a name in a formula in a cell, it throws an exception. The new DefinedNameConfusedForCellTest is a simple demonstration. The Regexp has been changed to ensure the name starts on a Word boundary, and to make sure it is not followed by a word character or period. This fixes the problem, and does not appear to cause any regression problems in the test suite. Closes #1263 |

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.
