The RefTools add-in extends Excel with new tools for reference operations, data manipulation and formatting. Capabilities include pasting, counting, hiliting, deleting or replacing values found in unsorted reference ranges, fuzzy searching, flexible data colorization using arbitrary or statistically-based color scales, set operations with pop-up statistics, and easy mass manipulation of shapes. For VBA development in Excel, RefTools includes cross-referencing of all macros, table-driven generation of custom toolbars and an autosave system allowing clean rebuilds of corrupted projects.
