In daily work and life, we often encounter such troubles: forgetting the password of an Excel file. This is really a headache, but don't worry. Today I will share with you some practical ideas for cracking Excel passwords and also introduce a great platform - the Document Password Recovery Master Platform (https://www.mima8.cn).

I. Common types and coping strategies of Excel passwords

Excel passwords are generally divided into opening passwords and worksheet protection passwords. The opening password is a password that prevents you from opening the entire Excel file, while the worksheet protection password restricts you from performing operations such as editing worksheets.

1. Opening password cracking

   • Brute force cracking method
   • This is a relatively "stupid" but sometimes effective method. In short, the program tries all possible character combinations to find the correct password. However, this method is very time-consuming, especially when the password is complex. If the password is a simple digital combination, such as 123456, it may be cracked quickly. But if it is a long password containing letters, numbers and special characters, it may take a long time, and it may not be possible to crack it within a reasonable time due to too many combinations.
   • Dictionary attack method
   • This method is like taking a dictionary to find a password. We have a pre-prepared "dictionary" containing a lot of common passwords. The program will try passwords from this dictionary one by one. This dictionary can be a collection of common password combinations collected according to experience or from the Internet, such as password, 12345678, qwerty, etc. If your password is relatively common, this method is likely to be successful. However, if your password is very personalized and not in the dictionary, this method will not work.
   • Using the hash value of the file to crack
   • This requires the use of tools such as the Document Password Recovery Master Platform. This platform has a great function of supporting hash decryption without uploading files. The hash value is like a "fingerprint" of the file password. Each file has a unique hash value. Through this hash value, the platform can try to crack the password without the need to upload the file. This avoids the risk of data leakage caused by uploading files. And this platform is inexpensive. It is a very affordable choice for many users who forget Excel passwords.

2. Worksheet protection password cracking

   • If you forget the worksheet protection password, we can try some built-in functions of Excel. Sometimes, we can bypass the protection by copying the worksheet content to a new worksheet. The specific operation is to create a new Excel file and then select the protected worksheet content in the original file and copy and paste it into the new file. However, this method may not work under some complex protection settings.
   • There is also a method of using VBA code (but this method requires you to have a certain understanding of VBA). Open the VBA editor in Excel (through the Alt + F11 shortcut key) and then enter some specific code to try to remove the worksheet protection. However, this requires certain programming knowledge. If the operation is improper, it may cause file damage, so be careful when using it.

II. Advantages of the Document Password Recovery Master Platform

1. Supporting hash decryption without uploading files
   • This is really very important. Many people are worried that uploading files during the password recovery process will lead to data leakage. And the Document Password Recovery Master Platform has solved this problem well. It only needs the hash value of the file to perform password recovery operations, which maximally protects the privacy of user files.
2. Low price
   • Compared with some other password recovery services, the price of this platform is very affordable. For ordinary users, they don't need to spend too much money to try to recover the forgotten file password. Whether it is an Excel file or the password recovery of Word, PDF, PPT, RAR, ZIP, 7z and other files, the price is within an acceptable range.
3. No need for manual operation
   • Once you submit relevant information (such as hash value), the platform will automatically perform password recovery operations. There is no need for you to stare at it all the time or perform complex manual interventions. This is very convenient for those users who don't understand technology. You just need to wait for the result.
4. No risk of data leakage
   • In addition to the advantage of not uploading files, the platform adopts strict security measures during the entire password recovery process. From the technical level to the management level, it ensures that user data will not be leaked out. This allows users to use the platform's services with confidence.

III. Ideas and platform universality of password recovery for other file types

1. Word file password recovery
   • For Word file passwords, the cracking ideas are similar to those of Excel files. You can also use brute force cracking method, dictionary attack method, etc. If you forget the opening password, the principle of brute force cracking method is the same. It is to try all possible character combinations. The dictionary attack method also relies on common password dictionaries to try. And the Document Password Recovery Master Platform can also be used for the recovery of Word file passwords. Its advantages of supporting hash decryption without uploading files, low price, etc. are also applicable to the recovery of Word file passwords.
2. PDF file password recovery
   • PDF file passwords have two situations, one is the opening password and the other is the permission password (restricting printing, copying and other operations). For the opening password, you can also try brute force cracking and dictionary attack. However, the encryption algorithm of PDF files is sometimes more complex and may require more time and computing resources. When processing PDF file password recovery, the Document Password Recovery Master Platform can still give full play to its advantages such as no need to upload files and low price. For the recovery of permission passwords, if it is a relatively simple permission setting, sometimes you can convert the PDF to other formats (such as Word) through some online tools or software and then perform operations, but this method may cause some format loss.
3. PPT file password recovery
   • If you forget the PPT file password, you can also use similar cracking ideas. Brute force cracking and dictionary attack are common methods. And in PPT files, if you forget the editing password, sometimes you can try to bypass it through some special functions of PPT software. For example, some PPT software can open files in read-only mode and then try to perform some operations to obtain editing permissions. The Document Password Recovery Master Platform is also a good choice for PPT file password recovery. Its various advantages can help users quickly and safely recover PPT file passwords.
4. RAR, ZIP, 7z file password recovery
   • The password recovery of these compressed files is relatively challenging. The brute force cracking method may take a long time in this case because the password space of compressed files is very large. The dictionary attack method may succeed if the password is within the dictionary range. The Document Password Recovery Master Platform also has good support for the recovery of these compressed file passwords. Its function of supporting hash decryption without uploading files can protect the privacy of user files when processing compressed files. The low price allows users to easily try to recover passwords. There is no need for manual operation and no risk of data leakage, which makes users feel very relieved when using it.

IV. Summary and suggestions

When facing the situation of forgetting file passwords, we have multiple methods to try. Whether it is specific cracking ideas for different types of files or the use of professional tools such as the Document Password Recovery Master Platform.

First, for password settings, we should try to choose passwords that are easy to remember but not easy to guess. Avoid using simple digital combinations or common words. If possible, you can use password management tools to help us manage passwords, so as to reduce the occurrence of forgetting passwords.

Second, when we really forget the password, don't panic. You can try some simple methods first, such as trying to copy the content to a new worksheet for worksheet protection password. If these methods don't work, then consider using password cracking tools.

Finally, when choosing password cracking tools or platforms, we must choose a safe, reliable and inexpensive platform like the Document Password Recovery Master Platform. Its advantages of supporting hash decryption without uploading files, no need for manual operation and no risk of data leakage can really make us save worry and worry during the process of recovering file passwords. I hope that when everyone encounters the situation of forgetting file passwords, they can successfully recover the password and make their files "usable" again.
