How to Auto-Format Dates and Capitalize Names in Adobe Acrobat PDF Forms
Question details
The user wants to automatically convert an eight-digit date entry into a standard formatted date with slashes and automatically capitalize names in a fillable PDF form.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Creating or editing a fillable PDF form to standardize user input for date and name fields.
- Observed behavior
- Without formatting, users manually input variations of dates and names. The goal is to automate the mm/dd/yyyy date format and apply proper casing to text fields.
Ensure you have access to the form editing tools in your PDF application and understand the basics of field properties before adding custom formatting scripts.
Apply Built-In Date Formatting and Custom Validation Scripts
Use the built-in date format for standard inputs, or apply a custom validation script to automatically convert an eight-digit string into a formatted date.
For standard date entries, built-in formatting handles the job perfectly. However, if you specifically need the form to accept an unbroken string of eight digits (e.g., 05272020) and automatically convert it to a separated date format (05/27/2020), you will need to utilize a custom JavaScript for validation.
Open the PDF form in your PDF editor and select the 'Prepare Form' or equivalent form editing tool.
Right-click the designated date field and select 'Properties' from the context menu.
Navigate to the 'Format' tab, choose 'Date' from the category dropdown, and select the 'mm/dd/yyyy' pattern.
To parse exact eight-digit entries without manual slashes, go to the 'Validate' tab, select 'Run custom validation script', and input a JavaScript code snippet designed to insert slashes after the month and day indices.

Best Practices for Name Capitalization in Forms
Avoid using automatic capitalization scripts for name fields, as personal names often follow unique casing rules.
Create and Format Fillable PDF Forms with WPS PDF
WPS Office provides a comprehensive built-in PDF editor that allows you to easily create fillable forms, adjust text field properties, and ensure cross-platform document compatibility.
- 1. Open your PDF document: Launch WPS Office and open the PDF file you wish to make fillable.
- 2. Access form tools: Navigate to the 'Form' tab on the top ribbon to access the form creation suite.
- 3. Insert form fields: Click on 'Text Field' and place it into your document where the date or name is required.
- 4. Adjust properties: Double-click the newly created field to open its properties, where you can modify formatting options to guide user inputs.

Frequently Asked Questions
Why shouldn't I use a script to automatically capitalize names in a PDF form?
Personal names do not always follow standard capitalization rules. For example, names like 'McCarthy' or 'de la Cruz' feature multiple or no capital letters at the beginning of words. Forcing a standard capitalization script will often modify these names incorrectly.
Can I format dates without using custom JavaScript?
Yes, you can use the built-in Date format settings in the field properties. By selecting the 'mm/dd/yyyy' format category, users who manually type the date with standard separators will have it standardized automatically without needing a script.
How do I access form field properties to change formats?
While in your PDF's form editing mode (such as Prepare Form), right-click the specific text or date field and select 'Properties'. From there, you can access the Format and Validate tabs to apply standard formats or custom scripts.
