Many Word document filenames cannot be directly used for archiving; the truly useful identifiers are often found within the main text. Taking Document ID as an example, this article explains how to import multiple docx files in HeSoft Doc Batch Tool , use regular expressions to match the identifier in the body text, and replace the filenames with the matched results. This method is suitable for batch organization scenarios such as reports, contracts, teaching materials, and archival documents, reducing the repetitive tasks of opening each Word file, copying the identifier, and manually renaming it.
When batch organizing Word files, a typical problem often arises: the file names in the folder are titles, subjects, or temporary names, but unit archiving, system import, or subsequent retrieval requires using the unique identifier within the document as the file name. For example, a batch of docx files named Cosmic_Distances.docx, Planets_and_Orbits.docx only reveals the subject from the file name, making it impossible to directly see the document ID. Only after opening the Word document do you find that a number like Document ID: 2JMM01GJ is already written at the top of the main text.
If the number of files is small, manually opening a Word file, copying the identifier, closing the document, pasting, and renaming might seem acceptable. However, when the file count grows to dozens, hundreds, or more, this repetitive labor consumes a significant amount of time and is prone to errors like copying mistakes, missed renames, accidental deletion of file extensions, and duplicate file names. This article will introduce an approach more suitable for office scenarios: using HeSoft Doc Batch Tool to extract target text from the Word document body using regular expressions and batch-set that text as the new Word file name.
Suitable Scenario: Extracting IDs from Word Body as File Names
The method in this article is applicable to all situations where the file name needs to be determined by Word document content. Common scenarios include: using the contract number from the contract body as the docx file name, using the sample number from a test report as the file name, using the student ID from student homework as the file name, using the project code from a project document cover as the file name, and using the Document ID from archival materials as the file name.
These scenarios share a common point: the target information exists in each document, but the original file names are not necessarily standardized; the target information usually has similar prefixes, positions, or formats that can be identified by rules. The advantage of regular expressions is that they do not require every identifier to be identical; instead, they identify the variable content across different documents through format rules.
In the screenshot, the pre-processing folder contains 5 Word files, all with the docx extension, named using English titles. These names are suitable for reading, but if you need to sort, upload, or archive them according to the document ID, conversion to ID-based naming is required.
Opening one of the Word documents, you can see that "Document ID: 2JMM01GJ" is marked in a red box at the top of the page. Here, "2JMM01GJ" is the text to be extracted. Since other Word files also have a similar Document ID, setting up the matching rule just once allows the software to batch-process all files.
Result Preview: Docx File Names Changed from Titles to Body IDs
After processing, the Word file names in the folder are no longer the original English titles but have become the IDs extracted from the document body. The screenshot shows the 5 files respectively changed to 2JMM01GJ.docx, 4HE73OR5.docx, CK83CAEJ.docx, KR8IHZD6.docx, and R6J2S6E6.docx.
This change indicates that the software completed three things: first, batch-reading the content of each Word document; second, locating the ID following "Document ID:" according to the regular expression; third, writing the matched ID into the file name while retaining the original Word extension. For users who need to batch-process office documents like docx and doc, this workflow is more stable than manual renaming one by one and is more suitable for repetitive tasks.
Operation Step 1: Find the Corresponding Function in HeSoft Doc Batch Tool
After launching HeSoft Doc Batch Tool , first look at the left navigation panel. The screenshot shows that the software provides categories like File Name, Folder Name, File Organizer, Word Tools, Excel Tools, PowerPoint Tools, PDF Tools, Text Tools, Image Tools, etc., positioning itself as software for batch office file processing. This task involves modifying Word file names, so we enter the File Name category.
On the File Name function page, select the 6th item: "Rename Word Files Using File Content". The description on this function card says "Batch use certain text from Word file content as the file name for that file," which perfectly matches our goal of renaming docx files by Document ID.
The key point of this step is not to choose the wrong function. If you just need to replace keywords in file names, you can use "Find and Replace Keywords in File Names"; if you want to insert fixed text into file names, you can choose "Insert Text into File Names". However, the naming source in this article is the Word document body content, so you need to enter "Rename Word Files Using File Content".
Operation Step 2: Import the Word Documents to be Renamed
After entering the function interface, the current task name "Rename Word Files Using File Content" is displayed at the top of the page. The button area above provides operations like Add Files, Import Files from Folder, Clear, More, etc. Choose the import method based on how your files are stored: use "Add Files" when files are scattered, and "Import Files from Folder" when files are concentrated in one folder.
The screenshot shows 5 records have been imported. The table lists information such as file name, path, extension, creation time, and modification time. You can see these files are all located in the D:\test directory with the docx extension. The summary at the bottom shows a record count of 5.
After importing, it's recommended to verify: confirm that the files in the list are the Word documents to be renamed in this batch, ensure the paths are correct, and check that no unrelated files have been added to the task. If a file shouldn't be processed, you can remove it using the delete icon in the operation column; if the entire import is wrong, you can clear the list and reselect. Batch processing is highly efficient, but the prerequisite is that the pending list is accurate.
After verification, click "Next" at the bottom of the interface to enter the processing options settings. This wizard-style flow reduces the chance of missed rules, allowing users to complete tasks in the order of selecting files, setting processing options, setting the save location, and starting processing.
Operation Step 3: Choose "Text Matched by Custom Formula"
After entering Step 2 to set processing options, first, set the search area. The interface shows three options: "First Line of Text", "First Barcode Image", and "Text Matched by Custom Formula". In this case, we need to extract the ID following "Document ID:" from the body text, not directly use the complete first line of text, so choose "Text Matched by Custom Formula".
The purpose of selecting this option is to tell the software not to simply take a fixed line as the file name, but to search for the target text in the document content based on the user-provided rules. This way, even if the ID appears within a paragraph of text, it can be accurately extracted as long as the surrounding format is stable.
Operation Step 4: Enter the Regular Expression to Match the Document ID
In the regular expression input box, enter the rule shown in the screenshot:
(?<=Document ID:)[0-9A-Z]+
This rule consists of two parts. The first part, (?<=Document ID:), specifies the matching position, meaning it only matches content following "Document ID:"; the second part, [0-9A-Z]+, specifies the ID format, meaning it continuously matches one or more digits or uppercase English letters. The result obtained this way will be IDs like 2JMM01GJ, 4HE73OR5, without including "Document ID:" itself in the file name.
The benefit of regular expressions is flexibility. If your Word document reads "Document ID:" followed by a space, or if the field name is changed to "Report ID", "Contract No.", "Sample No.", you need to adjust the expression based on the actual text. It is recommended to select a representative Word file first, observe the fixed content before and after the target text, and then write the matching rule.
For users unfamiliar with regular expressions, you can understand it as a filter condition: the preceding text is "Document ID:", and the subsequent continuous digits and uppercase letters are the content to be used as the file name. As long as each Word file conforms to this structure, batch naming will remain consistent.
Operation Step 5: Set the ID Position in the File Name
In the position area, you can choose "Overwrite the Entire File Name", "On the Left Side of the File Name", or "On the Right Side of the File Name". The screenshot shows "Overwrite the Entire File Name" is selected, meaning the extracted ID will directly replace the original file's main name.
Taking Cosmic_Distances.docx as an example, after the software matches 2JMM01GJ in the document body, the file name will become 2JMM01GJ.docx. The original "Cosmic_Distances" is replaced, while the .docx extension remains to denote the Word document format.
If you wish to retain the original title, you can also choose other positions based on your actual needs. For example, "On the Left Side of the File Name" could create a naming pattern like 2JMM01GJ_Cosmic_Distances.docx, and "On the Right Side of the File Name" could create one like Cosmic_Distances_2JMM01GJ.docx. However, the goal of the screenshot case is complete archiving by Document ID, so "Overwrite the Entire File Name" fits the requirement better.
Operation Step 6: Set the Save Location and Execute Batch Processing
After completing the processing option settings, continue to click "Next". The interface progress bar shows that the subsequent steps are setting the save location and starting processing. The save location determines where the processed files will be output. In practical work, if this batch of Word files is important, it is recommended to prepare a backup first or choose a new output location for processing. This way, even if the regular expression rule needs adjustment, the original files will not be affected.
Upon entering the start processing stage, reconfirm three key pieces of information: Is the number of files to be processed correct? Is the regular expression consistent with the fields in the Word body? Is the position option the intended "Overwrite the Entire File Name"? After confirmation, start processing. The software will read the contents of the docx files in the list one by one and apply the matching results to the file names.
After completion, open the target folder, and you will see that the file names have been batch-changed to the Document IDs. Comparing the before-and-after screenshots, a task that originally required opening and copying each file individually can now be completed in batch with a single rule setup.
FAQ: What to Note When Using Regex to Extract Word Text for Renaming
1. Why can't the regular expression match the ID? The most common reason is inconsistent field formatting. For example, the Word file actually uses "Document · ID", or there is a space after "Document ID", the colon is a Chinese colon, or the ID includes lowercase letters, hyphens, or underscores. In such cases, check the original body text first, then modify the rule.
2. Can any matched text be used in a file name? It is not recommended to directly use text containing special symbols as a file name. Windows file names have restrictions on certain characters. If the matched content contains characters like slashes, colons, asterisks, question marks, etc., it may cause renaming failure. ID-type texts are generally more suitable for file names.
3. What if multiple Word files extract the same ID? If two files generate an identical file name, a naming conflict may occur. It is best to confirm the uniqueness of the Document ID before processing. If uniqueness cannot be guaranteed, consider placing the ID on the left or right side of the original file name instead of overwriting the entire file name.
4. Do I need to open all the Word files first? You do not need to open them one by one. As long as the files have been added to the software list, the software will read their content during batch processing. Instead, it is advisable to close any Word documents being edited to avoid file occupation affecting the process.
5. Does this method only work for English ID numbers? No. The screenshot example uses a Document ID composed of uppercase letters and numbers, hence the use of [0-9A-Z]+. If your ID contains Chinese characters, numbers, dates, or other formats, you can write different matching rules based on the actual situation.
Tips for Increasing the Success Rate
Before formally processing a large number of Word files, it is recommended to test with 3 to 5 sample documents first. The samples should ideally cover different IDs, different titles, and possible format variations. After the test results are correct, batch import the complete folder. This allows early detection if the regular expression is too narrow or too broad.
Furthermore, before batch renaming, confirm that the extension has not been modified as part of the file name content. In the example of this article, the files are still docx files after processing, indicating that the software only replaced the file's main name and did not damage the Word format. For office documents requiring long-term archiving, retaining the correct extension is very important.
If the document body contains multiple similar fields, make the regular expression as precise as possible. For instance, if the body contains "Document ID", "Image ID", and "Section ID", use a more specific prefix for positioning to avoid matching the wrong ID. The more explicit the rule, the more reliable the batch processing.
Summary: Standardizing Word Naming Rules with Batch Processing Tools
Renaming files based on Word body content essentially transforms structured information inside the document into the external file name. For office documents like contracts, reports, archives, and teaching materials, this significantly improves retrieval, archiving, and handover efficiency.
Through HeSoft Doc Batch Tool , users can select "Rename Word Files Using File Content" within the File Name category, import multiple docx documents, choose "Text Matched by Custom Formula", input the regular expression (?<=Document ID:)[0-9A-Z]+, select "Overwrite the Entire File Name", and finally batch-turn the Document ID from the Word body into the file name.
If you are processing a batch of Word, docx, or doc files that need to be named by IDs, it is recommended to start by testing the rules with a small sample set, confirm the match results are correct, and then execute the batch operation. This reduces the time spent on repetitive opening and manual renaming, lowers the risk of human input errors, and makes file organization tasks more standardized and efficient.
