The most troublesome situation when batch archiving PDFs is when the file names are meaningless, and the barcode text inside the file is the actual number. Based on practical office scenarios, this article explains how to use HeSoft Doc Batch Tool to extract the first barcode image text in a PDF and overwrite it as the PDF filename. The article includes a comparison of effects before and after processing, function entry, file import, processing option settings, saving and processing precautions, helping users quickly complete automatic PDF renaming.
In file management, renaming may seem simple, but it’s often one of the most time-consuming steps. Especially when there are many PDF files, if the filenames are just system-generated serial numbers, such as 1.pdf, 2.pdf, 3.pdf, you can't directly determine the content. Many users have to open each PDF individually, find the barcode number on the page, and then manually modify the filename. This process is repetitive, inefficient, and may lead to inconsistencies between the filename and content due to misread numbers.
If the PDF page itself already contains a barcode, and the text corresponding to the barcode is the business number, a more efficient approach is to let office software automatically read this information and batch-rename files. This article uses HeSoft Doc Batch Tool as an example to explain how to batch-extract barcode text from PDFs and rename files, transforming PDFs in a folder from temporary names into identifiable and searchable number-based names.
Applicable Scenarios: Naming PDFs Based on Content Rather Than Original Filenames
This processing method is suitable for all scenarios where PDF content serves as the basis for naming, especially for materials with barcodes or barcode numbers on their pages. For instance, logistics and warehousing departments might need to organize documents by barcode number; quality inspection departments might need to archive PDFs by report number; educational and training institutions might need to manage documents by material number; administrative or archival staff might need to file scanned PDFs by their barcode number.
Unlike ordinary batch renaming, extracting PDF barcode text for renaming isn't simply about adding prefixes, suffixes, or replacing certain characters in the filename. Its key lies in obtaining naming information from the internal content of the PDF. The 'Rename PDF files using file content' feature provided by HeSoft Doc Batch Tool is a batch file processing capability designed specifically for this type of need.
Manual processing is acceptable when the number of files is small, but when there are dozens or hundreds of files, manual renaming is not only time-consuming but also increases the error rate. Using batch processing software transforms repetitive manual operations into a one-time rule setup, which the software then executes item by item according to the list.
Result Preview: Barcode Text Becomes the PDF Filename
First, let's look at the state before processing. There are 4 PDF files in the folder, named 1.pdf, 2.pdf, 3.pdf, 4.pdf. These names only indicate the file sorting order, not the file content, and they're not convenient for searching.
After opening a PDF, you can see a barcode in the top right area of the page, with the number text displayed below the barcode. The number in the screenshot is 20036655. The goal of this article is to automatically extract this kind of barcode text and use it as the new filename for the corresponding PDF.
After processing, the PDF names in the folder become 10026877.pdf, 20036655.pdf, 20100511.pdf, 33952100.pdf. As you can see, each PDF no longer uses a meaningless serial number, but is named using the barcode text extracted from the file content.
Step 1: Select 'Rename PDF files using file content'
After launching HeSoft Doc Batch Tool , go to the 'File Name' category on the left. This category contains multiple batch processing functions related to filenames, such as finding and replacing keywords in file names, inserting text into filenames, adding prefixes and suffixes to filenames, and adding the total page count of the document to filenames.
This time we are processing PDF files, and the naming source comes from the PDF content, so you should choose 'Rename PDF files using file content'. In the screenshot, this function card is selected, indicating its purpose is to batch-use certain text from the PDF file content as the filename for that file.
Selecting the correct function is important. If you were only making rule-based modifications to existing filenames, the original filenames would need to contain useful information; in this example, the original filenames are only 1, 2, 3, 4, offering no extractable value. Therefore, new filenames must be obtained through PDF content recognition.
Step 2: Add the PDFs to be processed to the task list
After entering the function page, the interface shows the first step is to select the records to be processed. At the top, you can see buttons like Add Files, Import Files from Folder, Clear, and More. Generally, if the PDFs to be processed are all in the same directory, using 'Import Files from Folder' is more convenient; if only a few scattered files need processing, 'Add Files' can be used.
After importing, the task table will list information such as file name, path, extension, creation time, and modification time. The screenshot shows 4 PDFs have been imported, named 1.pdf, 2.pdf, 3.pdf, 4.pdf, all with the .pdf extension, making a total of 4 records.
The purpose of this step is to let the software clearly identify the objects for this batch processing. After importing, check that the list is complete, the paths are correct, and the extensions are all .pdf. If you imported files that don't need processing, you can use the delete icon in the operation column to remove them; if the entire import is wrong, you can click 'Clear' and re-select.
After confirming everything is correct, click 'Next'. The first step is now complete, and the software will enter the processing rule setup phase.
Step 3: Set the search area to 'First Barcode Image'
On the processing options page, the most important setting is the search area. The screenshot shows three selectable options: First line of text, First barcode image, and Text matched by custom formula. This article aims to extract the text corresponding to the barcode, so 'First barcode image' is selected.
After selecting this option, the software will target the barcode image in the PDF as the recognition object and read the text content corresponding to the barcode. For the example PDFs, the barcode is located in the upper right area of the page, with the number displayed below it, which fits the processing logic of naming by barcode.
On the same page, you also need to set the position. The screenshot shows 'Overwrite the entire filename' is selected, meaning the barcode text will directly become the main part of the new filename. For example, after recognizing 20036655, the filename will become 20036655.pdf. This setting is suitable for scenarios where the original filename is meaningless, and you only want to keep the business number.
If you need to retain the original name in actual work, you can select 'To the left of the filename' or 'To the right of the filename' to add the recognized barcode text as supplementary information. However, in this case, overwriting the entire filename yields the most concise and best-suited result for archiving.
Step 4: Follow the workflow to set the save location and start processing
After completing the processing option settings, click 'Next' to continue. The interface workflow shows subsequent steps include setting the save location and starting processing. The save location is used to determine where the processed files will be output. Although the screenshot doesn't show the specific content of the save location page, it's reasonable to infer from the workflow that users need to complete the output location related settings in this step.
For important files, it's advisable not to risk operating directly on the only original copy. You can first copy them to a test folder or save the processing results to a separate directory, replacing the official files only after confirming the filenames are correct. This allows you to leverage batch processing efficiency while ensuring data safety.
Once you enter the 'Start Processing' phase, the software will perform recognition and naming for the PDFs in the list one by one according to the previously set rules. After processing, check the output folder to confirm whether the filenames have been generated according to the barcode text. If the results match expectations, you can batch-execute the same process on more PDFs.
Common Issues and Precautions
1. Do the PDFs need to have recognizable barcode images? Yes, the rule used in this example targets the first barcode image. If the barcode in the PDF is too small, blurry, distorted, or obscured, it may affect the recognition result. It's best to spot-check a few PDFs before processing.
2. Is there a one-to-one correspondence between barcode numbers and filenames? Under normal circumstances, the barcode text in each PDF will become the new name for that PDF. To avoid duplicate filenames, it's recommended to confirm whether the barcode numbers in different PDFs are unique.
3. Why does the processed filename have a .pdf extension? The software renames the main body of the filename; the PDF file's extension remains as .pdf. This way, the file type doesn't change, and it can still be opened with a PDF reader.
4. Is it possible just to append the number without overwriting the original filename? As seen in the screenshot, the position options include 'To the left of the filename' and 'To the right of the filename'. If business needs require retaining the original filename, you can choose an append mode; if only the barcode number is needed, select 'Overwrite the entire filename'.
5. How can I reduce risk before batch processing? It's recommended to process a small sample amount first, confirming that the first barcode image is indeed the target number and checking that the output names are correct. Once you've verified the rule is stable, then import the entire folder for batch processing.
