Hetman Excel Recovery recovers lost and deleted spreadsheets in XLS, XLSX and ODS formats saved by Microsoft Excel and OpenOffice. The tool is designed for heavy duty, helping ordinary computer users to successfully restore spreadsheets from formatted, repartitioned, corrupted and inaccessible storage devices. Its low-level data recovery algorithms are the same as used in the company's flagship tool, enabling surefooted recovery in cases that seem nearly hopeless. A special safety mode is available to handle unreliable and physically unstable hard drives. Hetman Excel Recovery offers a 100% success guarantee, delivering guaranteed recovery for spreadsheets appearing in the list of recoverable files. The tool performs a preliminary integrity check on all documents discovered on the disk before adding them to the list. This removes visual clutter and ensures that every file listed is actually 100% recoverable. Recovering information from formatted and repartitioned hard drives has its share of challenges. No file system is usually available, so a simple undelete operation is no longer possible. To facilitate the recovery from formatted volumes and repartitioned hard disks, Hetman Excel Recovery implements signature search analysis. During this analysis, the tool reads the entire content of the disk, matching information it reads in an attempt to detect the beginning of a recognized spreadsheet. Once a spreadsheet is detected, Hetman Excel Recovery calculates its length and validates the file's integrity. If, and only if, the spreadsheet passes the integrity check, the tool adds it to the list of recoverable files. Equipped with a highly sophisticated data recovery engine, program can still be used by ordinary mortals. The tool is controlled via a fully guided, step by step wizard. The wizard splits the recovery process into few easy steps, allowing every computer user to achieve the same high-quality results as a professional data recovery lab.
