Detect spreadsheet errors with the following tools: advanced formula direction highlighting, cell dependency hierarchical walkers, formula analysis, workbook summary reports, named range analysis, detection of empty or text cell references, and Nested IF views. Detect changes in models by using workbook or worksheet comparison reports. Summarize all the Excel documents found on a local or network drive and produce interactive reports. Minimize the introduction of spreadsheet errors by using policy editors to create user-defined rules that can be applied to all documents and report on those breaking best-practice rules; for instance prevent the use of Formula Arrays, insist on cell A2 being empty, limit the number of worksheets per document, or restrict the number of external references. EXChecker is a standalone Excel auditing application that does not required Excel to be installed.
