When the PDF file name is just a temporary number like 1.pdf, 2.pdf, etc., and the actual identifying information on the page is a barcode number, you can use HeSoft Doc Batch Tool to batch rename based on PDF content. This article covers the applicable scenarios, before-and-after effects, function entry, file import, barcode search area settings, file name overwrite rules, and precautions, helping users recognize the first barcode image in a PDF as text and automatically generate the corresponding numbered file name, thereby improving file archiving and retrieval efficiency.
When many departments receive PDF materials, the filenames are often not the final usable business names, but temporary names automatically generated by export systems or scanning devices, such as 1.pdf, 2.pdf, 3.pdf. This naming convention has little impact when the number of files is small, but once it involves batch archiving, uploading to systems, retrieval by number, or cross-checking with Excel ledgers, it significantly reduces efficiency. Especially when the PDF pages already contain barcode numbers, but manual intervention is still required to open the files and rename them one by one, this type of repetitive labor is highly unsuitable for long-term manual execution.
The method introduced in this article is to use the PDF content renaming capability in the office software " HeSoft Doc Batch Tool " to extract the barcode text from PDF pages and use it in batch as PDF filenames. In other words, the software will automatically name the files based on the barcode number in the PDF content, turning the filenames directly into business numbers for easier subsequent management.
Applicable Scenarios: Cases Where Internal PDF Numbers Need to Be Used as Filenames
If your PDF files contain clear barcodes internally, and the text number corresponding to the barcode is the unique identifier of the file, then the method in this article is highly suitable. Common scenarios include logistics waybill archiving, product label management, inventory document organization, exam material numbering, certificate PDF archiving, test report naming, batch organization of training materials, and classification of customer order files.
These tasks share a common characteristic: the filename itself is unreliable, and the number within the file content is the basis for management. When processing manually, one needs to open the PDF, find the barcode, view the number, copy or manually type the number, and return to the folder to rename it. The entire process is highly repetitive, and it is easy to mistakenly write the number of file A onto file B. Through batch processing tools, the software can uniformly perform reading, recognition, and renaming actions, freeing people from repetitive operations.
HeSoft Doc Batch Tool is a tool software designed for batch processing of office files. Its interface provides categories such as File Name, Folder Name, File Organization, Word Tools, Excel Tools, PDF Tools, Text Tools, and Image Tools. This article uses the PDF content renaming function found under the "File Name" category, focusing on solving the problem of "renaming PDF files based on their content."
Effect Preview: Original PDF Filenames Are Difficult to Identify
From the screenshot of the folder before processing, it can be seen that the PDF files are named only with numerical sequences, including 1.pdf, 2.pdf, 3.pdf, 4.pdf. While these names are simple, they cannot describe the file content, nor can they be used to determine the corresponding barcode number via the filename.
After opening one of the PDFs, a barcode can be seen within the page content, with the text number displayed below it. The example number in the screenshot is 20036655. For archiving purposes, this number is more valuable than the original filename, as it often corresponds to an order number, material number, or a business primary key in a system.
If filenames like 1.pdf continue to be used, locating a specific number later requires opening multiple PDFs to verify each one. If the file has already been renamed to barcode number.pdf, the number can be entered directly into the folder search box, greatly speeding up the location process.
Effect Preview: Named by Barcode Number After Batch Processing
After processing is complete, the filenames have changed from meaningless sequences to barcode numbers. For example, the screenshot shows 10026877.pdf, 20036655.pdf, 20100511.pdf, 33952100.pdf. Each PDF's filename corresponds to the barcode text in its content, making the number of each document visible in the folder at a glance.
This effect is particularly suitable for document repositories that require long-term storage and retrieval. Once filenames are standardized, they can be sorted, filtered, copied, uploaded, or reconciled based on the number without even opening the PDFs. For personnel who handle large volumes of PDFs daily, this not only saves a few minutes but continuously reduces repetitive labor and human error.
Operation Steps: From Function Selection to Barcode Recognition and Renaming
Step 1: Find the PDF Content Renaming Entry in the Software
After launching HeSoft Doc Batch Tool , first select "File Name" in the left navigation bar. Then find the "Rename PDF Files Using File Content" function card. In the screenshot, this function is located in the file name tool list, with a description prompting that it can batch-use certain text from the PDF file content as the file's filename.
Note that other filename-related functions also exist in the tool list, such as finding and replacing filename keywords, inserting text into filenames, adding prefixes/suffixes, and deleting text from filenames. These functions mainly process the original filename itself, whereas this article requires extracting the barcode number from the PDF content, so "Rename PDF Files Using File Content" should be selected.
Step 2: Import the PDFs to Be Batch Renamed
After entering the function, the current function name is displayed at the top of the page. The workflow is divided into selecting records, setting processing options, setting save location, and starting processing. First, import the PDF files in the "Select Records to Process" step. Buttons like "Add Files" and "Import Files from Folder" are provided in the upper right area of the interface.
If there are few PDFs scattered around, you can manually click "Add Files" to select; if the PDFs to be processed are concentrated in one folder, using "Import Files from Folder" is more suitable for batch operations. After importing, the list will show each file's name, path, extension, creation time, and modification time. The screenshot shows 4 records have been imported, all with the pdf extension.
The expected result at this step is: All PDFs needing to be renamed appear in the list, and no files that should not be processed are mixed in. It is recommended to check the record count, paths, and file extensions before clicking "Next" to ensure the processing scope is accurate.
Step 3: Choose to Extract Text from the "First Barcode Image"
After clicking "Next," you will enter the "Set Processing Options" page. In the "Search Area" section, the screenshot shows three options: "First Line of Text," "First Barcode Image," and "Text Matched by Custom Formula." Since the goal this time is to extract the barcode number from the PDF, you need to select "First Barcode Image."
This option determines where the software retrieves the new filename from. If a barcode exists on the first page or within the PDF document content, the software will try to recognize the first barcode image and use the recognition result as the basis for subsequent naming. For PDFs with only one main barcode on a page, this setting is the most direct and best meets the need to "name PDFs by barcode number."
If your PDF does not contain a barcode but rather a regular text number on the first line, you can choose "First Line of Text" based on the actual situation; if the number's location is more complex, then consider a custom matching method. In this article's example, the barcode is very clear, so selecting "First Barcode Image" is sufficient.
Step 4: Choose "Overwrite the Entire Filename"
In the lower part of the same settings page, the "Position" area provides options like "Overwrite the entire filename," "Left side of filename," and "Right side of filename." This example aims for the final filename to retain only the barcode number, no longer keeping the original sequence numbers like 1, 2, 3, 4, so "Overwrite the entire filename" should be chosen.
After selecting overwrite, the file's main name will be replaced by the barcode text, but the PDF extension will remain .pdf. This results in barcode number.pdf. For archiving and retrieval, this naming method is concise, uniform, and avoids interference from the original sequence numbers in judgment.
If your business process requires retaining the original filename as traceability information, you could also consider appending the barcode text to the left or right. For example, placing the number before the original filename to form a structure like "20036655-1.pdf." However, the processing result in the screenshot example completely replaces the original filename with the number, so this article explains based on "Overwrite the entire filename."
Step 5: Set the Save Location and Execute Batch Processing
After completing the processing options, continue by clicking "Next" at the bottom of the page. Following the workflow bar, it will proceed to "Set Save Location," then to "Start Processing." It is crucial to carefully choose the output location at this step, especially when processing important files in batch. You can first output to a new folder and confirm the results are correct before replacing the files in the original directory.
Once processing starts, the software will process the PDFs one by one according to the record list: reading the file content, finding the first barcode image, recognizing the barcode text, and generating a new name according to the "Overwrite the entire filename" rule. After processing is complete, check the save location to see the results, where you'll find the PDFs have been named by their numbers.
Common Questions and Considerations
1. Must the PDF contain a barcode?
This article demonstrates renaming based on barcode text, so the PDF must contain a recognizable barcode image. If the PDF has no barcode but only regular text numbers, you should select a different search area based on the interface options, such as the first line of text or a suitable text matching method.
2. Can it be processed if the barcode is not on the first page?
From the screenshot, it's confirmed that the software provides the "First Barcode Image" option, but the specific recognition scope depends on the PDF structure. To ensure stable results, it's advisable to test with a few sample files first. If all PDFs have a consistent barcode location and layout, the success rate of batch processing is usually easier to control.
3. Should I back up before batch renaming?
Backing up is recommended, especially for first-time processing or when dealing with a large number of files. Although batch processing can significantly boost efficiency, renaming is an operation that affects the file management structure. Keeping original files first or outputting to a new location can prevent situations where recovery is difficult after an incorrect setting.
4. Can the recognized number be directly used for Windows filenames?
Barcode numbers are typically numbers or letters and are generally suitable for use as filenames. However, if the recognition result contains special characters not allowed in system filenames, it might affect naming. It is recommended to confirm the output effect using sample files before actual processing.
5. How is this different from batch naming Word or Excel files?
The content structures of PDF, Word, and Excel differ, leading to different reading methods. Word might involve the body content of doc or docx files, Excel might involve cell content, while the scenario in this article involves barcode images in PDFs. When choosing a tool, you should match the corresponding function based on the file type and content source to avoid using the wrong entry.
Summary: Turn PDF Barcode Numbers into Filenames to Improve Archiving Efficiency
Using the barcode text within PDF content to batch rename PDF files essentially delegates the processes of manual number recognition and manual renaming to office software for automatic completion. Through HeSoft Doc Batch Tool , users can first import PDFs, then select "First Barcode Image" as the search area, and use "Overwrite the entire filename" to generate uniform number-based filenames.
For teams needing to manage large amounts of PDF materials, this method ensures filenames are consistent with their file content, reduces repetitive labor, lowers input errors, and improves the efficiency of subsequent retrieval, archiving, uploading, and reconciliation. If you also have a batch of temporarily named PDFs, and each file contains a barcode number, you can follow the steps in this article to test a few samples first, confirm the results are correct, and then batch process all files.
