How to Use a Decimal Point Instead of a Comma in PDF Forms
Question details
The user needs to configure a PDF form field so that it accepts numbers using a decimal point (period) rather than a comma.

- Device & OS
- not provided
- Scenario
- Setting up or filling out a PDF form that requires numerical data entry with specific decimal formatting.
- Observed behavior
- Depending on the field's number-format settings or the operating system's regional settings, the form defaults to using a comma as the decimal separator.
Check your computer's system-wide regional and language settings, as PDF software often inherits default number formatting preferences directly from the operating system.
Modify the Number Format Settings in PDF Field Properties
Change the specific properties of the text field within your PDF editor to enforce a period as the decimal separator.
PDF forms allow creators to dictate how numbers are formatted within specific text fields. By editing the field properties, you can explicitly define the separator style regardless of the user's default locale.
Launch your PDF editor (such as Acrobat or WPS PDF) and open the document in 'Prepare Form' or 'Form Edit' mode.
Right-click the specific text field you want to modify and select 'Properties' from the context menu.
In the Properties dialog box, click on the 'Format' tab located at the top.
Choose 'Number' from the 'Select format category' drop-down menu.
Look for the 'Separator Style' option and choose the format that uses a period for the decimal point (for example, '1,234.56'). Click 'Close' to save the changes.
Adjust Your Operating System's Regional Settings
Change your system's region settings to globally modify the default decimal separator from a comma to a period.
Create and Edit Interactive PDF Forms with WPS Office
WPS Office features a powerful built-in PDF editor that makes it incredibly easy to design fillable forms, customize text field properties, and manage number formatting rules.
- 1. Open your document: Launch WPS Office and open your PDF file using the WPS PDF tool.
- 2. Go to the Form tab: Click on the 'Form' tab in the top navigation ribbon to access all interactive form creation tools.
- 3. Edit field properties: Double-click any existing text field, or insert a new one, to open the 'Text Field Properties' dialog box.
- 4. Customize formatting: Switch to the 'Format' tab to specify your preferred number style and enforce a period as the decimal separator.

Frequently Asked Questions
Why does my PDF form automatically change my decimal point to a comma?
This generally happens because the PDF software reads your computer's regional settings. If your system is set to a locale that traditionally uses a comma as the decimal separator (like many European regions), the PDF form will automatically format numbers to match.
Can I force a specific decimal separator regardless of the respondent's computer settings?
Yes. As the form creator, you can go into the text field properties, select the 'Format' tab, choose the 'Number' category, and explicitly set the Separator Style to one that uses a period. This overrides the respondent's local system settings.
Do these number formatting rules apply when the PDF is printed?
Field formatting rules dictate how the data is handled and displayed digitally. Once the form is filled out and printed (or flattened), the text is permanently set exactly as it appeared on the screen at the time of printing.
