General Questions About Excel Recovery

What types of Excel files can you recover?

The program supports all major Excel file formats including .xls files from Excel 97-2003 and .xlsx files from Excel 2007 and newer versions. It also recovers .xlsm files that contain macros and .xlsb files in binary format. The software handles files created in any Excel version from 1997 to the current release. Even files with complex elements like pivot tables, embedded objects, and external links can be processed. The recovery engine recognizes the internal structure of each format and applies the appropriate extraction method for maximum data preservation.

Can you recover a file that does not open at all?

Yes, in most cases this is possible. The program scans the damaged file structure at the binary level and extracts available data without requiring Excel to open the file first. Even if Excel shows error messages like «Cannot open file» or «File is corrupted», recovery chances remain high. The software bypasses Excel’s standard opening procedure and reads data directly from the file structure. Success rates exceed 90% for files with moderate damage. Only files with complete structural destruction may be unrecoverable.

How long does file recovery take?

Time depends on file size, damage level, and computer performance. The process usually takes 30 seconds to 5 minutes for standard spreadsheets under 10 MB. Large files with complex formulas, multiple sheets, or embedded objects may take up to 15 minutes. Files over 50 MB might require additional processing time. The program shows a progress bar so you can track recovery status. Faster processors and SSD drives significantly reduce waiting time. We recommend closing other programs during recovery for best performance.

What if the program cannot find my file?

Make sure you selected the correct folder for scanning during the file selection step. Check if the file is hidden in the system by enabling «Show hidden files» in Windows Explorer options. Sometimes the file may be in the Recycle Bin or Windows temporary folder located at C:\Users[Username]\AppData\Local\Temp. Try using the search function in Windows to locate the file by name or extension. If the file was recently deleted, check the Recycle Bin first. Network drives and cloud storage folders may require different access methods.

Can you recover a deleted Excel file?

The program works with damaged files that exist on disk, not completely deleted ones. You need special data recovery utilities for files removed from disk without backup. However, if the file exists on disk but will not open due to corruption — we can help effectively. When Windows deletes a file, it often remains on disk until overwritten by new data. For deleted file recovery, consider tools like Recuva or EaseUS Data Recovery first. Once recovered, if the file is damaged, our software can repair it.


Technical Questions and Compatibility

Which Windows versions are supported?

The program works on Windows 10, Windows 11, and Windows 8.1 with full functionality. Windows 7 with latest security updates is also supported but may have limited features. Both 32-bit and 64-bit versions of Windows are compatible. The software requires at least 2 GB of RAM and 100 MB of free disk space for installation. Windows Server editions from 2012 onward are also supported for corporate environments. Older versions like Windows XP or Vista are not supported due to security and compatibility limitations.

Does the program work on Mac?

The macOS version is currently in development and not yet available for public release. Mac users can use a Windows emulator like Parallels Desktop or Boot Camp to run the program on their machines. Virtual machine solutions like VMware Fusion also work effectively for this purpose. Another option is running Windows on a separate partition using Boot Camp for native performance. We recommend checking the official website regularly for macOS version updates and release announcements.

Do I need internet to use the program?

No. The program works locally on your computer without requiring constant internet connection. Internet is only required for downloading the installer file and activating your license key initially. Once installed and activated, all recovery operations happen offline on your machine. This ensures your sensitive data never leaves your computer during the recovery process. You can use the program on computers without internet access after completing the initial setup and activation steps.

Can I install the program on multiple computers?

This depends on your specific license type purchased from the official store. Single-user license allows installation on one computer for personal or business use. Corporate licenses allow installation on multiple workstations within one organization. Volume licensing options exist for businesses needing deployment across many computers. License transfers between computers are possible but require deactivation on the old machine first. Contact support for details about upgrading your license to cover additional installations.

Do I need special skills to use this?

No. The program interface works for users of any skill level from beginners to advanced professionals. The step-by-step recovery wizard guides you through the entire process automatically with clear instructions. Each screen explains what action to take next in simple language. No technical knowledge about file structures or recovery methods is required. Video tutorials and help documentation are available within the program for additional guidance. Most users complete their first recovery within minutes of installation.


Data and Security Questions

Is it safe to transfer files for recovery?

The program works locally on your computer without uploading files anywhere. Files do not go to third-party servers, which guarantees complete confidentiality of your data. All processing happens on your machine using your computer’s resources. This approach meets business security requirements and protects sensitive financial information. No data is stored, logged, or transmitted during the recovery process. You maintain full control over your files throughout the entire operation.

Are formulas and formatting saved after recovery?

In most cases, yes. The program preserves formulas, cell formatting, charts, graphs, and conditional formatting rules. Complex elements like pivot tables and data validation are also maintained when possible. However, some elements may be lost with severe damage to specific file sections. Macros in .xlsm files are preserved but may require re-enabling after recovery. Embedded objects like images and OLE objects are recovered when the damage is not extensive. Preview function lets you check recovered content before saving.

What about password-protected files?

The program can recover file contents but does not remove or bypass password protection. You need to know the password to access the recovered file after the process completes. If you forget the password, third-party password recovery tools may help but are not guaranteed. The recovery process works on the encrypted file structure without needing the password. However, the output file retains the original security settings and password requirements. Consider removing passwords from important files before damage occurs for easier recovery.

Can you recover files from USB drives or external disks?

Yes, the program works with any storage device that shows up in your system as a drive letter. This includes USB flash drives, external hard disks, SD cards, and network drives. We recommend copying the file to your computer hard drive first for faster processing and stability. Direct recovery from external devices may be slower and more prone to interruptions. Ensure the external drive is properly connected and recognized by Windows before starting. Damaged external drives may need professional data recovery services first.

What happens to the original file after recovery?

The original file stays completely unchanged on your storage device. The program creates a new recovered file that you save to your chosen folder location. You select the output destination during the recovery process before saving begins. This approach protects your original file from any additional damage during recovery. You can run multiple recovery attempts with different settings on the same original file. We recommend keeping the original file until you confirm the recovered version works properly.


License, Payment, and Support

Is there a free version of the program?

Yes, a free trial version is available for download from the official website. It lets you scan files and preview recovered data before buying the full version. The trial shows exactly what content can be recovered from your damaged files. However, saving recovered files requires purchasing a license key. This approach lets you verify recovery success before spending money. Trial version has no time limit but limits the amount of data you can save.

How much does the full version cost?

Prices vary by license type and current promotions on the official store. Single-user licenses typically range from $49 to $99 depending on features included. Corporate and volume licenses have custom pricing based on number of installations. Discounts often exist for new users, seasonal promotions, and bundle offers. Check the official Stellar Repair for Excel website for current pricing details. Educational and non-profit organizations may qualify for special discount programs.

Can I get a refund if the program does not help?

Yes, the company offers a 30-day money-back guarantee if the program cannot recover your files. You need to contact support within 30 days of purchase with details about your issue. The support team may suggest alternative recovery methods before processing refunds. Refunds are processed to the original payment method within 5-10 business days. This guarantee demonstrates confidence in the software’s recovery capabilities. Keep your purchase receipt and license information for refund requests.

How do I get technical support?

Support is available by email and through the contact form on the official website. Response time is usually 24-48 hours during business days. Priority support options exist for corporate customers with faster response guarantees. The website also includes knowledge base articles and video tutorials for common issues. Support team members are trained specialists in data recovery and Excel file structures. Include your license key and file details when contacting support for faster assistance.

Do updates come free?

Yes, you get free minor updates and bug fixes during your license period automatically. Major versions with new features may require separate payment or upgrade fees. Update notifications appear within the program when new versions become available. Installing updates ensures compatibility with latest Excel versions and Windows updates. Some updates include improved recovery algorithms for better success rates. We recommend keeping your software updated for best performance and security.


Problem Solving and Errors

What if the program freezes during recovery?

Try restarting the program and computer to clear any temporary memory issues. Make sure you have enough free disk space on both source and destination drives. Close other running programs to free up system resources for the recovery process. If the problem continues, try recovering the file in smaller segments if possible. Contact support with details about where the process stops for specific guidance. Running the program as administrator may resolve permission-related freezing issues.

Why does the recovered file open with errors?

This may mean serious damage to specific sections of the original file structure. Try recovering the file again with different recovery mode settings available in the program. Some modes prioritize data completeness while others focus on structure integrity. Contact support for individual help with severely damaged files. In some cases, partial recovery of certain sheets or data ranges is possible. The preview function helps identify which parts of the file recovered successfully before saving.

Can you recover multiple files at once?

Yes, the program supports batch processing for multiple files in a single session. You can add several files to the recovery queue and process them sequentially automatically. This saves time when dealing with multiple corrupted files from the same incident. Each file is processed independently with its own preview and save options. Batch processing works best when files have similar damage patterns. Monitor the queue progress and check each recovered file before closing the program.

What does «File is irreversibly damaged» mean?

This is a rare message indicating the file structure is so damaged that recovery is impossible. It means critical sections of the file containing essential data are completely destroyed. In such cases, contact professional data recovery specialists for advanced options. Sometimes earlier versions or backup copies may exist that can be recovered instead. Cloud storage services often keep version history that might contain usable copies. Consider implementing better backup strategies to prevent total data loss in the future.

How do I prevent file damage in the future?

Create regular backups using automated systems or cloud storage with version history. Use uninterruptible power supplies to protect against sudden power outages during file operations. Do not interrupt file saving processes or close Excel unexpectedly while working. Update Excel and Windows to the latest versions for security and stability improvements. Avoid storing important files on unreliable storage devices or network locations with frequent disconnections. Enable Excel’s AutoRecover feature and configure it to save frequently.
