In daily work and life, we often encounter such troubles: the Excel files created with hard work cannot be accessed because the password is forgotten. At this time, do you feel particularly frustrated? Don't worry. Today I will share with you some practical skills of Excel password recovery and also introduce a super good platform - Document Password Recovery Master Platform (https://www.mima8.cn).

I. Common situations of Excel password recovery

Let's first understand why there will be Excel file password loss. Sometimes it may be that after setting the password for a long time, we have forgotten what the password was set at that time; it may also be that we took over a file set with a password by others, but the other party did not inform the password. No matter which case, the password is like an invisible barrier, separating us from the important data in the file.

II. Basic methods of Excel password recovery

1. Brute force cracking method
   • This is a relatively direct method, but it also takes a long time. Simply put, it tries all possible character combinations to find the correct password. However, when the password is relatively complex, this method may take a lot of time. It is like in a huge password maze, trying each possible passage one by one.
   • But our Document Password Recovery Master Platform has its advantages. The platform adopts advanced algorithms that can accelerate the brute force cracking process to a certain extent. And the platform has the function of supporting hash decryption without uploading files, which greatly improves security and there is no need to worry about the risk of file data leakage.
2. Dictionary attack method
   • This method is based on a dictionary file containing a large number of commonly used passwords. It will try passwords one by one from this dictionary to see if it can match. Many people choose some relatively common combinations when setting passwords, such as birthdays, simple number sequences, etc. In this case, the dictionary attack method may be very effective.
   • When the Document Password Recovery Master Platform performs dictionary attacks, it also has its own optimizations. Its dictionary is constantly updated and contains more new common password combinations. And the price of the platform is low, which is very affordable for ordinary users.

III. Advantages of Document Password Recovery Master Platform

1. Support hash decryption without uploading files
   • This is really important. Many people are worried that during the password recovery process, their file data will be leaked. And the Document Password Recovery Master Platform uses hash decryption method. It does not need to upload the file itself. Only the hash value of the file is needed to perform the password recovery operation. This is like adding a security lock to your file data and eliminating the risk of data leakage from the source.
2. Low price
   • We all know that finding professional password recovery services may cost a lot of money. But on the Document Password Recovery Master Platform, you only need to spend a small amount of money to enjoy professional password recovery services. This is very attractive for those users who are in a hurry to recover files because they have forgotten the passwords.
3. No need for manual operation
   • Once you submit the relevant information of the file that needs to recover the password (such as hash value, etc.) on the platform, the platform will automatically perform the password recovery operation. There is no need for you to stare at it all the time or perform complex manual interventions. This saves your time and energy. You can do other things and just wait for the recovery result of the platform.

IV. Word, PDF, PPT password recovery

In fact, there are many similarities with Excel password recovery.

1. Word password recovery
   • In the case of Word file password loss, you can also consider the brute force cracking method and the dictionary attack method. The brute force cracking method may be relatively fast to find the answer when facing simple passwords, and the dictionary attack method is very effective for those users who are used to using common words or phrases as passwords.
   • The Document Password Recovery Master Platform is also applicable to Word file password recovery. Its algorithm can quickly analyze and recover the password of Word files. And the advantages of the platform, such as security, low price and no need for manual operation, are also reflected in Word file password recovery.
2. PDF password recovery
   • PDF files often exist as important document formats. If you forget the password of a PDF file, whether it is the opening password or the permission password, it will bring inconvenience to us.
   • Brute force cracking and dictionary attack methods are also feasible here. However, due to the different encryption methods of PDF files, the Document Password Recovery Master Platform has been optimized for the encryption characteristics of PDF files. It can accurately identify the encryption type of PDF files and thus recover passwords more efficiently.
3. PPT password recovery
   • Beautiful PPTs that cannot be opened or edited due to password problems are really a pity. PPT password recovery can also try the methods mentioned above.
   • The Document Password Recovery Master Platform performs well in PPT password recovery. It can handle password recovery problems of PPT files of different versions, whether it is early PPT versions or the latest versions.

V. Compressed file (RAR, ZIP, 7z) password recovery

1. RAR file password recovery
   • RAR files are a format that we often use to compress and store a large number of files. If you forget the password of a RAR file, the files inside are like locked in an encrypted box.
   • The brute force cracking method is a feasible method for RAR file password recovery. But because the encryption strength of RAR files is relatively high, it may take more time. The Document Password Recovery Master Platform adopts an efficient algorithm to handle RAR file password recovery. On the premise of ensuring security, it tries its best to improve the recovery speed.
2. ZIP file password recovery
   • ZIP files are very common compressed file formats. When the password of a ZIP file is lost, we can also seek password recovery methods.
   • The dictionary attack method may have good results in ZIP file password recovery, especially for those simple password ZIP files. The Document Password Recovery Master Platform also has the advantages of low price, no need for manual operation and safe and reliable in ZIP file password recovery.
3. 7z file password recovery
   • 7z files are loved by many people because of their high compression ratio. But if you forget the password of a 7z file, you will face the problem that the file cannot be decompressed.
   • Brute force cracking and dictionary attack methods are also applicable to 7z file password recovery. The Document Password Recovery Master Platform has been optimized for the encryption characteristics of 7z files and can quickly and accurately recover the password of 7z files.

VI. Summary

When facing various file (Excel, Word, PDF, PPT, RAR, ZIP, 7z) password loss situations, we have some basic recovery methods that can be tried. But if you want to recover file passwords more efficiently, safely and affordably, the Document Password Recovery Master Platform (https://www.mima8.cn) is a very good choice. Its advantages of supporting hash decryption without uploading files, low price, no need for manual operation and no data leakage risk can meet the needs of a large number of users. I hope that when you encounter file password loss situations, you can successfully regain the access right of files and no longer be troubled by password problems.
