When multiple Word, docx, or doc documents contain similar but not identical content, opening each file to find and delete it can be very time-consuming. This article uses the example of batch deleting English uppercase acronyms and numbers to demonstrate how to use the "Find and Replace Keywords in Word" feature in HeSoft Doc Batch Tool , leveraging regular expressions for fuzzy matching and leaving the replacement content blank to achieve batch deletion. This method is suitable for cleaning up repetitive identifiers in templates, materials, contracts, and course documents.
In daily office work, it is common to encounter this situation: a folder contains many Word documents, each with similar numbering, English abbreviations, course codes, department acronyms, annotation marks, or residual template content. They are not necessarily exactly the same, and you cannot easily find and delete them one by one using a single fixed word. For example, in the screenshot of multiple docx files, the body text contains three-letter uppercase English abbreviations like BOT and ELA, as well as numbers like 60. If you open each file one by one, then manually search, delete, and save, it is not only time-consuming but also prone to missing entries.
This type of problem is better solved with a batch processing tool. HeSoft Doc Batch Tool is a batch document processing software designed for office scenarios. Its core value lies in reducing repetitive operations, allowing you to centrally process Word, docx, and doc files that would usually require manual handling, by importing them and applying rules uniformly. This article, with the help of screenshots, will demonstrate how to use the "Find and Replace Keywords in Word" feature to batch delete keywords from multiple Word documents using regular expressions for fuzzy matching.
Applicable Scenarios: When to Batch Delete Word Keywords with Regex
Regular find-and-replace is suitable for deleting fixed text, such as replacing "confidential" with nothing in all documents. However, if you need to delete a category of content, not just one specific word, you need to use regular expressions. Regex can match text by patterns, making it ideal for handling content that is "similar in format but different in specifics."
For example, the following scenarios can all potentially use the method described in this article:
- Batch delete three-letter uppercase English abbreviations from multiple Word documents, such as BOT, ELA, ABC, etc.
- Batch delete numerical codes, course durations, version numbers, or temporary markers from docx documents.
- Clean Word files exported from a system by uniformly removing codes, abbreviations, and placeholders from templates.
- Remove confidential numbers or identifiers from large numbers of contracts, proposals, reports, or course materials before distribution.
- Perform unified cleaning on multiple doc and docx files, avoiding omissions from manual, one-by-one searching.
The rules used in this article's example are [A-Z]{3} and \d+. Here, [A-Z]{3} can be understood as matching three consecutive uppercase English letters; \d+ can be understood as matching one or more consecutive digits. Replacing these matched contents with nothing achieves the goal of batch deletion.
Effect Preview: Content to be Deleted Exists in Multiple Word Documents Before Processing
From the screenshot of the files before processing, you can see that the current folder contains multiple Word documents like 1.docx, 2.docx, 3.docx, 4.docx, 5.docx, 6.docx, etc. They all need the same cleaning rules applied. If processed one by one, the repetitive effort is very obvious.
After opening one of the Word documents, you can see that there is content in the body text that needs to be deleted. A three-letter uppercase abbreviation like BOT appears in the title position, and the body text also contains ELA, 60, and others. The red arrows in the screenshot have marked these key positions that need processing.
The characteristic of this type of content is: some are English uppercase abbreviations, some are numbers; they may not be exactly the same across different documents, but the format pattern is relatively consistent. Therefore, if you rely solely on exact search for a specific word, efficiency is low. Using regular expressions for fuzzy searching and leaving the replacement content blank is the only way to process this entire category of text at once.
Effect Preview: Keywords Batch-Deleted After Processing
After processing, when you open the Word documents again, you can see that the original BOT in the title has been deleted, and matched content like ELA and 60 in the body text has also been removed. The main content of the document remains, only the keywords matching the rules have been cleaned out.
From the results perspective, this is not simply deleting a single fixed word but deleting a category of text based on rules. For example, three-letter uppercase letters were identified and cleared, and numeric content was also identified and cleared. For batch cleaning of Word and docx documents, this method is more stable and better suited for handling large numbers of files compared to manual, one-by-one processing.
Operational Step 1: Enter the Word Tool and Select the Find-and-Replace Feature
After opening HeSoft Doc Batch Tool , select "Word Tools" from the tool category on the left. In the function list on the right, find "Find and Replace Keywords in Word". This feature is for batch finding and replacing keywords within Word file content, and deletion can be achieved by leaving the replacement content blank.
The purpose of selecting this function is to centralize the content processing of multiple Word documents into a single task, rather than opening each file individually. For scenarios with a large number of files, this step significantly reduces repetitive clicking, copy-pasting, and saving operations.
In this example, we need to process English abbreviations and numeric content in multiple docx files, so after entering the "Find and Replace Keywords in Word" function, we can start importing the files to be processed.
Operational Step 2: Add the Word, docx Files to be Processed
After entering the function page, the software will display a processing wizard. The first step is "Select records to process". In the upper right corner of the page, you can see the "Add Files" and "Import Files from Folder" buttons. If the number of files is small, you can click "Add Files" to select them manually; if there are a large number of Word documents in a single folder, using "Import Files from Folder" is more convenient.
The screenshot shows that 6 docx files have been imported, and the list displays information such as serial number, name, path, extension, creation time, and modification time. This list allows you to confirm whether the correct files are awaiting processing, for example, if 1.docx through 6.docx have all been added to the task.
The expected result of this step is: all Word documents requiring batch keyword deletion appear in the list. If you find that unnecessary files have been imported, you can remove them using the action column in the list; if the files are incomplete, continue adding or import from a folder. After confirming everything is correct, click "Next" at the bottom to proceed to the processing rule settings.
Operational Step 3: Choose to Use Formula for Fuzzy Text Search
After entering the "Set Processing Options" page, you need to set the search method first. In the screenshot, you can see that search methods include "Exact Text Search" and "Use Formula for Fuzzy Text Search". This example needs to use regular expressions to delete a category of content, so "Use Formula for Fuzzy Text Search" should be selected.
The purpose of selecting "Use Formula for Fuzzy Text Search" is to let the software match content based on rules, rather than just matching fixed strings. For example, the document might contain different abbreviations like BOT, ELA, ABC, XYZ, which would be troublesome to type in one by one; using [A-Z]{3} can match three consecutive uppercase English letters, thereby achieving fuzzy deletion.
Two rules have been entered in the "Keyword List to Find" on the left side of the screenshot:
- [A-Z]{3}: Used to match three consecutive uppercase English letters.
- \d+: Used to match one or more consecutive digits.
These two rules are the core of this batch deletion. The software will search the content of the imported Word documents for matches to these rules and perform replacement according to the replacement list on the right.
Operational Step 4: Leave Replacement Content Blank to Achieve Batch Deletion
On the right side of the same settings page, you can see the "Replacement Keyword List". The prompt in the screenshot says "Leaving it blank means deletion". This indicates that if the replacement content corresponding to a search rule is empty, the software will delete the matched content instead of replacing it with new text.
Therefore, in this example, to delete the content matched by [A-Z]{3} and \d+, there is no need to fill in replacement text on the right. Keeping it blank is sufficient. After processing this way, the three-letter uppercase English abbreviations and consecutive digits in the documents will be removed.
Note that the matching range of a regular expression depends on the rule itself. [A-Z]{3} will match three consecutive uppercase letters; if other three-letter uppercase abbreviations exist in the document, they might also be deleted. \d+ will match consecutive digits; if there are numbers in the body text you do not wish to delete, you need to adjust the rule beforehand. Before batch processing, it is recommended to test the effect on a few files first before processing all of them.
Operational Step 5: Set the Save Location and Start Processing
After completing the settings for search rules and replacement content, click "Next". Following the page wizard, the subsequent steps will enter "Set Save Location" and "Start Processing". From the wizard flow, you can see that the software will let users first confirm the output location before executing the batch processing task.
The operational purpose of this step is to avoid directly overwriting the original files, which could lead to irretrievable data loss. In actual office work, it is recommended to save the processed files to a separate output folder, or to back up the original Word documents before processing. This way, even if the regular expression rules are set too broadly, you can revert to the original files and readjust.
After clicking start processing, the software will process the Word documents one by one according to the previously imported file list. Compared to manual operation, the advantage of batch processing lies in unified rules, faster speed, and easier result review. For dozens or hundreds of docx files, the efficiency improvement will be even more significant.
Common Questions and Important Notes
1. Why choose "Use Formula for Fuzzy Text Search"?
Because this article aims to delete not a single fixed keyword, but a category of content that follows a pattern. For instance, BOT and ELA have different specific characters, but they both belong to the category of three-letter uppercase abbreviations, so using [A-Z]{3} can match them uniformly.
2. Is leaving the replacement content blank the same as entering a space?
No. The prompt in the screenshot says "Leaving it blank means deletion", which means when the replacement list on the right has no content, the matching text will be deleted. If a space is entered, it usually results in replacing the text with a space, potentially leaving unwanted blank areas in the document.
3. Could [A-Z]{3} accidentally delete other content?
It is possible. It will match three consecutive uppercase English letters, so it is only suitable for scenarios where it is confirmed that all such abbreviations need to be deleted. If you only want to delete abbreviations within a specific range, you should further narrow down the rules or test on sample documents first.
4. Will \d+ delete all numbers?
\d+ is used to match consecutive digits. Regular numbers entered in the body text are usually matched. If the document contains dates, serial numbers, amounts, page numbers, or other digits that must be preserved, use it cautiously to avoid deleting too much content at once.
5. Can both doc and docx be processed this way?
The screenshot example processes docx files. For batch find-and-replace scenarios in Word documents, common needs include docx, doc, and other formats. In practice, the files should be those recognized and processable by the software's import list.
Summary: Using Office Software for Batch Word Processing to Reduce Repetitive Deletion Tasks
The key to batch deleting fuzzy keywords from multiple Word documents lies in two points: first, use office software that supports batch processing to import files uniformly; second, use regular expressions to describe the pattern of the text to be deleted. In this article's example, using the "Find and Replace Keywords in Word" feature of HeSoft Doc Batch Tool , selecting "Use Formula for Fuzzy Text Search", entering [A-Z]{3} and \d+, and leaving the replacement content blank, allows for the batch deletion of three-letter uppercase abbreviations and numeric content.
If you are handling a large number of docx, doc, or Word documents, continuing to manually delete items file-by-file is not recommended. A more efficient approach is to first organize the files to be processed, back up the original documents, then use the batch find-and-replace function to set rules and execute uniformly. This reduces repetitive labor and makes the document cleaning process more controllable.
