Please download the macro enabled file, and there you will check the VBA code inside it along with the sheet layout.
✅Step 1: Preparing the PDF Form
I started by opening the PDF form "8594" and enabled form editing mode (via Tools - Forms - Edit Layout) to reveal the field names (textboxes and checkboxes).
Each form element has a unique name, which I manually copied into the Excel sheet to use as placeholders.
✅Step 2: Setting Up the Excel Sheet
In the Excel file, I created a dedicated sheet for the form.
Column B and C (hidden by default) contain the placeholder names copied from the PDF.
Column B is linked to values in Column D.
Column C is linked to values in Column E.
This structure creates a clear key-value mapping—placeholders as keys and user input as values.
Checkboxes in the form are linked to specific cells in Excel. The linked cells have white text to remain hidden from users while still functioning correctly.
✅Step 3: Writing the VBA Code
The code resides in a module named after the PDF form.
It begins by identifying the worksheet containing the form data.
The name of the target PDF is provided in the code, and the script constructs the full file path using the active workbook’s directory.
It checks whether the original PDF file exists before proceeding.
✅Step 4: Automating the PDF Filling
A PDF object is created and the file is opened.
The code finds the last row of data in Column B, then loops through each placeholder:
It identifies each textbox in the PDF using the name in Column B.
It retrieves the corresponding user input from Column D and fills the form.
A similar loop is run for Column C and Column E.
Special conditions are included to handle checkboxes—checking or unchecking them based on Boolean (TRUE/FALSE) values.
✅Step 5: Saving the Completed PDF
After populating all fields, the filled PDF is saved as a new copy in the same folder as the original form.
A confirmation message is displayed once the process is completed.
