Recovery of the xls file
Restoring an xls file can be quite a difficult task, especially if the file is damaged or corrupted. However, there are several ways to try to recover data from such a file.
1. Use the "Open and restore" function of the Microsoft Excel program: If you have installed the Microsoft Office program with the Excel application, you can open the damaged xls file through the "File -> Open" menu. At the same time, a dialog box will appear with a list of available options for its editing and the possibility of performing an automatic data integrity check.
2. Windows preview version: Some versions of the Windows operating system have a tool called "Preview", which allows you to preview the contents of various types of files without the need to launch the corresponding programs. You can use this tool to display the contents of your damaged xls file and copy the necessary data to a new Excel sheet.
3. Third-party programs that restore the XLS/XLSX format: There are many third-party programs that claim to be able to successfully recover information from corrupted .xls files. Some of them include Recovery Toolbox for Excel, Stellar Phoenix Excel Repair, and SysInfoTools Excel Recovery.
4. Use online services: There are also various online services for restoring xls files that can help restore data from a damaged file. One of the examples is the Online File Repair service (https://onlinefilerepair.com/ru/excel-repair-online.html).
It is important to note that the result may depend on the degree of file damage and the effectiveness of the selected method or program for its recovery. Therefore, backing up data is the best way to prevent information loss in such situations.
