Regional Settings

The Regional Settings allow you to change the locale and timezone for your workbook.


About Locale and Timezone

IronCalc will try to match your browser's language and locale when possible. If your language is not supported, it will default to English (en-US).

By default, the locale follows the display language unless it has been manually changed in a workbook. This means that changing the language from the language switcher will also update the locale in workbooks that still use the default setting.

Locales and timezones are workbook-specific. If you create a new workbook, it will use the default locale and timezone—not those of your previous workbook.


How to Change the Locale

  1. Click on the locale indicator in the bottom-right corner of the canvas.
    • A drawer will open on the right side.
  2. Select the locale for your workbook.
    • This will affect how numbers, dates, and times are displayed. For instance, the number 1,234.56 in en-GB will appear as 1.234,56 in es-ES.

How to Change the Timezone

By default, IronCalc uses your browser's timezone. This can be changed from the Regional Settings drawer.

Changing the timezone will affect date- and time-related functions, such as TODAY() and NOW().
