If the same type of useless lines repeatedly appears in multiple TXT files, such as appendix lines, table of content lines, log marker lines, or export description lines, manually deleting them can be a huge waste of time. This article introduces a more efficient office processing method: using HeSoft Doc Batch Tool , you can import multiple TXT files into a text tool, set the keywords to search for, and leave the replacement content empty, thereby batch deleting all complete lines containing these keywords. This is suitable for office document organization and text data cleaning.
Many people encounter a seemingly simple but time-consuming issue when handling text materials: a folder contains a batch of txt text files, and each file has a few lines of unwanted content, all of which share the same or similar keywords. For example, the sample text file includes appendix lines like Annex A, Annex B, Annex C, and Annex D. The task is to delete these lines from all text files, keeping only the main body table of contents and subsequent content.
Using a regular text editor usually involves opening the first file, searching for Annex A, deleting that line, then searching for Annex B and deleting it, and so on. After saving, you open the second file and repeat the same actions. This is manageable when there are only a few files, but once there are dozens or more, the repetitive labor becomes very noticeable, and it's easy to miss a deletion or make a mistake with just a moment's inattention.
This article introduces a processing method more suitable for office scenarios: using the text tool function in " HeSoft Doc Batch Tool " to batch find complete lines containing specified keywords in text files and delete these lines by leaving the replacement content empty. Its value isn't just "being able to delete"; more importantly, it can process multiple files at once, reducing repetitive operations and improving text cleanup efficiency.
Applicable Scenarios: When do you need to batch delete entire lines in TXT files by keyword?
Deleting entire lines by keyword is suitable for processing text files with relatively regular structures. "Regular structure" means that although the specific content of the lines to be deleted isn't identical, they all contain certain fixed keywords. As long as they can be identified by keywords, you can automate the process with batch processing tools.
- Cleaning appendix or table of contents lines: For example, deleting entire lines containing content like Annex A, Annex B, Appendix, or table of contents notes.
- Deleting specified records from system logs: For example, deleting log lines that contain keywords such as debug, trace, test, or ignore.
- Organizing batch-exported txt data: For example, deleting repetitive header lines, explanation lines, copyright lines, or prompt lines that appear at the beginning of each file.
- Removing invalid data: For example, deleting lines that contain identifiers like "null value," "invalid," "temporary record," or "voided."
- Batch standardizing text materials: For example, removing fixed-format annotation lines from multiple document files to make the main text cleaner.
The focus of this method is "processing entire lines." If a line contains the specified keyword, the software will delete or replace the entire line, not just the keyword itself. Therefore, it is particularly suitable for batch clearing line-level content that doesn't need to be kept.
Effect Preview: Comparison before and after batch processing
Before Processing: Multiple txt files await uniform cleanup
In the folder before processing, you can see multiple text files, including 1.txt, 2.txt, 3.txt, 4.txt, and 5.txt. These files belong to the same batch of materials pending processing and are suitable for batch operations. For office workers, the ideal processing method is not to open them one by one but to import them uniformly, set rules uniformly, and output results uniformly.
Before Processing: File content has multiple lines containing target keywords
Opening 1.txt shows that the text starts with the Annexes title, followed by lines containing Annex A, Annex B, Annex C, and Annex D. These lines are the content to be deleted this time. Although each line has different English descriptions following it, as long as the line contains the corresponding keyword, it can be identified by the rule.
This is also a typical use case for batch deleting keyword lines: the entire line doesn't need to have identical content, only a specified keyword. For example, regardless of the description following Annex A, as long as the line contains Annex A, it will be deleted.
After Processing: Lines hitting the keywords are removed; the main text is preserved
The screenshot after processing shows that the lines originally containing Annex A to Annex D have been deleted, while the subsequent Contents and numbered directory are retained. That is, the tool only deleted the complete lines matching the rules, without clearing out other body text content along with them.
This processing result is very useful for document organization. It can quickly remove useless lines while keeping the overall readability of the file, avoiding the formatting chaos caused by manual copy-pasting or manual deletion.
Operation Steps: Batch deleting lines containing keywords
Step One: Open the text tool function in the office software
After launching HeSoft Doc Batch Tool , you can see multiple office file processing categories on the left side, including File Name, Folder Name, File Organization, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, etc. Since the processing objects this time are txt text files, select "Text Tools."
On the Text Tools page, find the "Find and replace complete lines in text files based on keywords" function. The function description in the screenshot indicates that this tool can batch delete or replace complete lines containing a certain keyword in text files with new text, which corresponds exactly to the need to "batch delete all lines containing keywords."
After selecting this function, all subsequent settings will revolve around "complete lines." Pay special attention here not to mistakenly select the regular keyword replacement function, as regular replacement usually only processes the words themselves, not entire lines.
Step Two: Import the multiple TXT files to be processed
Upon entering the function page, the software first requires you to select the records to be processed. The upper right of the page provides entry points like "Add File," "Import Files from Folder," "Clear," and "More." In the example, five txt files have been imported; the list displays 1.txt to 5.txt in order, along with their corresponding paths and extensions.
If your files are scattered in different locations, you can use "Add File" to select them individually; if the files are all concentrated in one folder, using "Import Files from Folder" is more efficient. After importing, it's recommended to check the file paths in the list to confirm you haven't selected the wrong directory and haven't inadvertently included files that shouldn't be processed.
After this step is complete, click "Next" at the bottom to enter the rule settings. At this point, the software knows which files to process; next, you need to tell it "what content to find, and how to handle it when found."
Step Three: Enter the keywords to delete, and leave the replacement content empty
On the "Set Processing Options" page, you first see the "Search Method." The screenshot shows "Precise Text Search" is selected. In the "List of Keywords to Find" below, the example has entered Annex A, Annex B, Annex C, and Annex D in succession. On the right is the "List of Keywords After Replacement," with a clear prompt stating "Leaving blank means deletion."
Therefore, to achieve batch deletion of entire lines, the settings are very straightforward: enter the keywords to find on the left and leave the replacement list on the right blank. This way, during processing, the software will look for complete lines in each txt file; if a line contains any keyword from the left list, that line will be deleted.
Taking the screenshot as an example, the text line includes content like "Annex A Food and drink standards...". Although the entire line is not exactly equal to Annex A, it will be matched and deleted because it contains Annex A. Similarly, lines containing Annex B, Annex C, and Annex D will also be deleted.
If you need to delete Chinese content, you can set it up in the same way. For example, to delete lines containing "Test Data," enter "Test Data" in the keyword list; to delete lines containing "Invalid Record," "Temporary Line," or "Duplicate Header," enter these keywords respectively. It is recommended to place one keyword per line to facilitate later review and maintenance.
Step Four: Set the output location and execute batch processing
After setting the keywords, click "Next." Following the process prompts at the top of the page, the subsequent steps are "Set Save Location" and "Start Processing." Since this is an operation that batch modifies file content, it's recommended to save the processed files to a separate location. This makes it easy to distinguish them from the original files and convenient for verification after processing.
Once in the start processing step, the software will process the txt files one by one according to your imported file list. The processing logic is: read the text content, find complete lines containing the specified keywords, delete the hit lines, and then generate the processed file. After completion, you can open one of the result files for a spot check to confirm that the target keyword lines no longer appear.
If the spot check results are correct, you can then use or archive all the result files. For a large number of text files, this method can compress what might have taken dozens of minutes or even hours of manual operation into a single batch task.
Frequently Asked Questions and Notes
1. Why is the entire line missing after deletion, and not just the keyword?
Because the function selected this time is "Find and replace complete lines in text files based on keywords." Its processing target is the entire line that hits the keyword, rather than the keyword itself. This characteristic is precisely the key to batch cleaning line-level content.
2. Can the keyword list include multiple entries?
Yes, it can. In the screenshot, four keywords were set simultaneously. In actual use, you can continue adding more as needed. Multiple keywords are suitable for handling various types of useless lines, such as deleting table of contents lines, comment lines, and test marker lines simultaneously.
3. Can content be filled in the replacement keyword list on the right?
If your goal is to delete entire lines, the right side should remain empty, because the interface prompt states "Leaving blank means deletion." If you fill in content, the processing result might change to replacing the entire hit line with new text. Deletion and replacement are two different goals, so be sure to confirm your objective before operating.
4. How to reduce the risk of accidental deletion?
The most important thing is to make the keywords specific enough. For example, to delete the Annex A line, enter Annex A, not just Annex. Entering just Annex could delete all lines containing Annex, including title lines or other descriptive lines you might want to keep. It is also recommended to test with a small number of files first before processing.
5. Is this method suitable for Word doc or docx files?
This article demonstrates processing for txt text files. The structure of Word doc and docx files is different from plain text and cannot be simply equated to txt. If you need to batch process Word documents, you should use the Word-related tools in the software, or first convert the format according to actual needs before processing.
Summary: Reducing repetitive text cleanup work with batch processing
Batch deleting entire lines containing keywords in TXT files is essentially about turning repetitive, manual search-and-delete processes into rules. Using HeSoft Doc Batch Tool , you can first import multiple text files, then set the keywords to find, leave the replacement content empty, and finally batch output the processing results. The entire process is clear, verifiable, and suitable for office workers to use repeatedly for similar tasks.
If you often need to clean up txt logs, document directories, exported text, or batch text data, it is recommended to organize the keywords you need to delete into a list in advance and then use the method introduced in this article for batch processing. This not only saves time but also reduces the omissions and errors caused by manual editing, making file organization work more efficient and reliable.
