Splitting Invoices By Invoice Number Using AutoSplit™ Pro Plug-in
It is very common task to split a PDF document that contains multiple invoices or reports. The AutoSplit™ software can split a PDF documents that contain variable-length invoices, account statements, and reports into separate PDF files. The following tutorial is going to show how to take a PDF file with multiple invoices and split it. Each output PDF file will contain only a single invoice and will be named using the corresponding invoice number.
Input Document Description
The input PDF document contains multiple invoices of variable length. The goal is to split it into multiple documents that contain each invoice as a separate file and name it, using invoice numbers from the first page of each document for file names.
Splitting Approach
It is common that each invoice has its separate page numbering, typically in a form of "Page N of M" text pattern. The easiest method to split such documents into separate files is to use "Page 1 of " or “1 of N” text as a separator. Since this text always occurs on the first page of each invoice, it is natural to use it as a reliable separator. Using “Page 1 of” is the very common method for splitting invoices or statements.
You need a copy of Adobe Acrobat Standard or Professional along with AutoSplit Pro plug-in installed on your computer in order to use this tutorial. You can download trial versions of both Adobe Acrobat and AutoSplit Pro.
Step 1 - Open a PDF File
Start Adobe® Acrobat® application and open a PDF file using “File > Open…” menu.

Step 2 - Open “Split Document Settings” Menu
Select “Plug-ins > Split Document…” from the main Acrobat® menu to open “Split Document Settings” dialog.

Step 3 - Select Splitting Method
Check “Use separator” box, select “Page With Matching Text” from the list of available options.
Next, press “Options…” button.

Step 4 - Configure Splitting Parameters
Enter “1 of” into “Find what” box. The document will be split at pages that contain “1 of …” text. This is a common way to detect a first page of each invoice since it often contains "Page 1 of N" labels. Check “Search for text only inside a specified area on the page” box to limit text search to a specific area.
Press “Edit Area…” button to define a working area.

Step 5 - Define Text Location On the Page
Define page area where a separator text (“1 of N”) is located by drawing a box around it. Try to select an area that does not include any other text. Use "Zoom" tool to enlarge part of the page for a more precise selection.
Click “OK” once done.

Step 6 - Confirm Split Method Settings
Press “OK” button in the “Separator Page by Text Search” dialog.

Step 7 - Specify Output File Naming
Set "Name prefix:" to "No Prefix" option. Make sure "Base filename" box is empty and there are no any entries in "Append to name:" list.

Step 8 - Define a Naming Scheme for Files
Press "Add..." button again. We have to specify an output filename.
Press “Add…” to start defining an output naming scheme.

Step 9 - Select Filenaming Option
The filename is also extracted from the first page of each output document as it is often the case.
Select "Text From Location" option and press "Next" button.

Step 10 - Define Page Area For Extracting File Name
Position mouse at the page area where you want to extract text for the filename (where invoice number is located) and press and hold left mouse button. Draw a box around the area and release mouse button. Now you have defined the area for text extraction. If you made a mistake simply do it again.
Press “OK” button once done.

Step 11 - Specify an Output Folder
Specify an output folder via "Browse..." button.
Click ‘OK” button to proceed.

Step 12 - Start Splitting Process
Click “OK” in the dialog box to start the process.

The “AutoSplit Results” dialog appears on screen once a processing is completed.
The “Results” dialog will list output files that were created during the processing.
Click “Open Output Folder” to inspect the results.
