Text files encompass many types, with the most common being TXT Notepad. We usually use it to store notes, organize materials, or save online articles. In actual processing, we may also encounter situations where we need to clean entire sections of text content, especially when multiple paragraphs contain structurally similar keywords. Manually searching and deleting paragraph by paragraph is not only time-consuming but also prone to omissions. In such scenarios, we can use fuzzy matching to quickly identify paragraphs containing structurally similar keywords, thus achieving batch cleaning.
Here's how to use formulas to fuzzily find corresponding text or numbers, quickly delete the entire segment containing that keyword, and greatly improve document processing efficiency!
When do you need to delete entire paragraphs containing similar text or numbers in a TXT file?
Remove sensitive information
When batch processing text data such as customer feedback or survey results, it may contain information like phone numbers, ID numbers, or order numbers. When privacy protection is required, entire segments containing such information must be deleted.
Clean up numbered paragraphs
Systems or applications generate many files during operation. These files often contain paragraphs marked with numbers, times, or keywords. For ordinary users, this content is redundant. Deleting paragraphs containing these texts makes files cleaner and easier to read.
Delete irrelevant information
When organizing Chinese documents or articles in TXT format, you may need to delete paragraphs with marker numbers or specific keywords. These paragraphs may have no actual meaning, and deleting them makes the article's focus more prominent.
