Both of the methods mentioned above can yield excellent results in recovering data from corrupted Excel files. The choice of which method to use often depends on the severity of the corruption.

Additionally, if there are numerous Excel files to recover, the data recovery process can be time-consuming.

In such cases, using a specialized third-party Excel file recovery tool can be a more efficient and reliable solution. These tools are designed to handle a wide range of corruption scenarios and can often recover data from severely corrupted Excel files quickly and accurately. Therefore, for quick and precise Excel file recovery, especially when dealing with highly corrupted files or a large volume of files, it is advisable to consider using a dedicated Excel recovery tool.

Professional third-party Excel recovery tools are designed to provide comprehensive solutions for all types of Excel data loss situations, including highly corrupted files. These specialized tools often have advanced algorithms and features that can handle even the most challenging cases of corruption, ensuring a higher success rate in data recovery.

So, when dealing with Excel files that are severely damaged or in scenarios where built-in methods fail to retrieve your data, it’s wise to turn to professional Excel recovery tools for a more robust and reliable solution. These tools can help you recover your data effectively and efficiently, regardless of the extent of file corruption.
