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.

Solution 1Recommended

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.

1
Enter form editing mode

Open the PDF form in your PDF editor and select the 'Prepare Form' or equivalent form editing tool.

2
Access field properties

Right-click the designated date field and select 'Properties' from the context menu.

3
Set the built-in date format

Navigate to the 'Format' tab, choose 'Date' from the category dropdown, and select the 'mm/dd/yyyy' pattern.

4
Apply a custom script for 8-digit inputs

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.

Scripting Requirement: Converting an unbroken eight-digit string requires basic JavaScript knowledge to properly parse the string length and insert the slash characters at the correct positions.

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.
