The program's advanced data recovery capabilities include repairing formulas, hyperlinks, comments, diagrams, pictures, VBA macros and cell data of workbook. One more advantage is that the document repaired with File Internals Excel Repair will look exactly as it was intended to look, as the software restores formatting, cell height and width. The program's intuitive interface makes recovering corrupt XLS files extremely easy for non-techies.
