When multiple Word, docx, or doc documents contain characters with similar formats but not entirely identical content, such as English abbreviations, serial numbers, numbers, code snippets, etc., opening each file one by one to find and delete them is very time-consuming. This article takes HeSoft Doc Batch Tool as an example to demonstrate how to use the "Find and Replace Keywords in Word" feature, leveraging regular expressions for batch fuzzy matching and deletion of keywords across multiple Word files, thereby reducing repetitive operations and improving document cleaning efficiency.
When organizing a large number of Word documents, a common situation arises: the content that needs to be deleted is not exactly the same fixed phrase, but rather text with a certain pattern. For example, a 3-letter uppercase abbreviation before a document title, numerical lists within the body text, or varying codes or identifiers across different files. If you open each docx or doc file individually to manually find and delete them, it is not only inefficient but also prone to omissions.
The method introduced in this article uses the batch find and replace feature for Word in the office software HeSoft Doc Batch Tool . By using regular expressions for fuzzy matching and leaving the replacement content empty, you can batch delete keywords from multiple Word documents. This method is particularly suitable for batch cleaning of text with similar structures and clear rules but non-fixed specific content.
Applicable Scenarios: Which Word Content is Suitable for Batch Deletion with Regular Expressions
Regular expressions are suitable for processing text that is "regular but not identical." Compared to ordinary exact searches, regex can match a category of content at once, making it very suitable for batch processing multiple Word, docx, and doc files.
- Delete fixed-format abbreviations before titles: For example, 3-letter uppercase abbreviations like BOT, ELA, ABC.
- Delete numbers in the body text: For example, the 60 in "60 hours," or list numbers, serial numbers, monetary amounts, etc., within the document.
- Delete codes with a consistent format across different files: For example, product codes, course codes, project codes.
- Clean up redundant markers in batch-generated documents: For example, template variables, import identifiers, placeholders, etc.
In the example for this article, 6 Word documents need to be batch processed to delete keywords that match the rules: 3 consecutive uppercase letters and numerical content.
Effect Preview: Before and After Processing Comparison
Before Processing: Multiple docx files contain the rule-based text to be deleted
The example folder contains 6 Word documents, with filenames from 1.docx to 6.docx. They all require the same keyword cleanup operation.
Opening one of the Word documents shows that the title contains a 3-letter uppercase abbreviation like BOT, and the body text contains numerical content like 60. This content might not be exactly the same in every file, but the format is regular, making it suitable for batch deletion using regular expressions.
After Processing: Matched Keywords are Batch Deleted
After processing is complete, the original uppercase letter abbreviations in the titles have been deleted, and the numbers in the body text have also been removed. Because the replacement keyword list for this operation was empty, the matched content is cleared directly, achieving the effect of "batch fuzzy deletion of Word keywords."
Operation Steps: Using Regular Expressions to Batch Fuzzy Delete Word Keywords
Step 1: Enter the Word Tools and Select "Find and Replace Keywords in Word"
After opening HeSoft Doc Batch Tool , select Word Tools on the left side. Find and click "Find and Replace Keywords in Word" in the tool list. This function is used for batch finding and replacing keywords in Word file content, and batch deletion can also be achieved by "replacing with empty."
The purpose of this step is to enter the functional module specifically for processing text find and replace in Word. For scenarios requiring batch modification of docx and doc file content, it is very important to select the correct tool first.
Step 2: Add the Word Files to be Processed
After entering the function page, the software will display the processing flow, including "Select Records to Process," "Set Processing Options," "Set Save Location," and "Start Processing." In the first step, you can click Add Files, or batch import Word documents via Import Files from Folder.
As seen in the screenshot, 6 docx files have been imported in the example. The list displays information such as file name, path, extension, creation time, and modification time. After confirming the files are correct, click the Next button at the bottom of the page to enter the processing option settings.
If a particular file does not need to be processed, it can be removed in the operation column on the right side of the list to prevent accidental processing.
Step 3: Select "Use Formula to Fuzzy Find Text"
On the "Set Processing Options" page, find Find Method. There are two methods available: "Exact Text Search" and Use Formula to Fuzzy Find Text. Since this example aims to delete content that is regular but not fixed, select Use Formula to Fuzzy Find Text.
The "Use Formula to Fuzzy Find Text" here can be understood as using regular expressions to match text. It doesn't just search for one specific fixed word but matches a category of text based on the entered rules.
Step 4: Enter the Regular Expressions to Find
In the left-side Keyword List to Find, enter the rules to match. The example enters two lines:
- [A-Z]{3}: Matches 3 consecutive uppercase English letters, e.g., BOT, ELA, ABC.
- \d+: Matches one or more digits, e.g., 60, 100, 2026.
These two rules will search for qualifying text in the Word documents separately. For batch deleting non-fixed keywords, entering different rules on separate lines can cover multiple content types at once.
Step 5: Leave the Replacement Keyword List Empty to Achieve the Deletion Effect
The right side is the Replacement Keyword List. The prompt in the screenshot says "No list entry means deletion", so this example does not fill in any replacement content. This way, when the software processes the files, it will replace the content matched on the left with nothing, effectively deleting these keywords from the Word documents.
This step is critical for achieving "batch deletion": if content is filled in on the right, the software performs a replacement; if the right side is left blank, it performs a deletion.
Step 6: Continue to the Next Step, Set the Save Location, and Start Processing
After confirming the search method and regular expressions are correct, click Next. Following the interface flow, the next steps are to set the save location for the processed files and then enter the start processing phase.
It is recommended to save the processed files to a new folder to distinguish them from the original files and to facilitate spot-checking after completion. Once done, open the generated Word documents to check the results and confirm that the matched keywords have been deleted.
Common Questions and Precautions
1. Why use regular expressions instead of exact search?
If the keywords to delete in each Word document are exactly the same, an exact search is sufficient. However, if the keywords vary, such as different 3-letter uppercase abbreviations, different numbers, or different codes, regular expressions are more suitable. Regular expressions can match a category of content by rule, reducing repetitive input and repeated operations.
2. Does an empty replacement list always mean deletion?
As indicated by the prompt "No list entry means deletion" marked in the replacement keyword list area, to delete the matched content in this function, do not enter any content in the right-side replacement list.
3. Regular expressions must be entered carefully to avoid accidental deletion
The broader the matching range of a regular expression, the easier it is to match content you don't want to delete. For example, \d+ will match all numbers in the document, which might also delete dates, page numbers, monetary amounts, and reference numbers. Before formal batch processing, it is recommended to test with a small number of files first, and process all files after confirming the effect.
4. Are docx, doc, and other Word files supported?
The screenshot example processes docx files. In actual Word document organization, the common file formats users encounter include docx and doc. Before operation, you can first gather the Word files to be processed into a single folder, and then import them in batch via "Add Files" or "Import Files from Folder."
5. It is recommended to keep a backup of the original files before processing
Batch file processing is highly efficient, but it also means the impact can be significant if the rules are set incorrectly. Therefore, it is advisable to back up the original Word documents before starting, or save the output files to a new directory to avoid overwriting important data.
Summary: Reduce Repetitive Word Document Cleanup Work with Batch Processing Tools
Through the "Find and Replace Keywords in Word" function of HeSoft Doc Batch Tool , the work that originally required opening Word documents one by one, manually searching, and manually deleting can be converted into a one-time batch process. For scenarios where rule-based keywords exist across multiple docx and doc files, combining this tool with regular expressions enables more flexible fuzzy matching and batch deletion.
If you frequently need to clean up list numbers, abbreviations, variables, numbers, or other patterned text in Word documents, you can follow the steps in this article: import the files first, then select "Use Formula to Fuzzy Find Text," enter the regular expressions, and leave the replacement content empty. This allows you to quickly complete batch fuzzy deletion, significantly reducing repetitive labor and improving office document processing efficiency.
