The find and replace function in TXT text documents can only replace or delete certain specified text content. If we want to delete an entire line containing specified text, we can only manually find and delete them one by one, which is very inefficient. Below is a very simple method that can batch delete entire lines containing specific text with one click, and can also process many TXT files at the same time, saving time and effort!
In daily work, we often encounter situations where we need to delete an entire line or paragraph of text in a document, for example, deleting all lines containing the word "备注", or deleting entire lines that contain "免责声明".
In such cases, the built-in find and replace function of a TXT editor is limited; it can only find and delete specific keywords, but cannot delete the entire line containing those keywords. Therefore, we need a simpler and more convenient method to perform this operation. Below, we will teach you the specific steps.

Steps to Batch Delete Entire Lines Containing Specified Text in TXT Files
1. Open HeSoft Doc Batch Tool , select Text Tools → Find and replace complete lines in text files based on keywords.

2. Click Add Files or import files from a folder to add all TXT documents.

3. Select Exact Text Search, and in the keyword list on the left, enter the specified text. For example, if we want to delete all entire lines containing "Answer", enter "Answer" here. Leaving the right text box blank indicates deletion.

4. After processing, click Save Location to view. All entire lines containing the specified text in the TXT documents have been cleanly deleted.

Besides the method above, you can also use Word to batch delete paragraphs in documents, but the operation is more complex. This is because we first need to convert the TXT files into Word documents, and then use wildcards to perform batch deletion. If there are many documents to process, this is very time-consuming and inefficient.
The method introduced above is not only simple and efficient but also error-proof, because many people do not understand how to use wildcards and can easily accidentally delete other content, which then requires even more time to correct. Using professional tools allows you to precisely batch delete specific lines, and it is very easy to get started with—even beginners can handle it easily!
