SpellCheck dialog mode comes with default localization support which allows it to customize the display of text within the SpellCheck dialog in a user-specific culture and locale. The SpellCheck control can be localized in specific culture using the common API locale along with the collection of localized words defined for that culture using the ej.SpellCheck.Locale [culture-code].

By default, the SpellCheck control is localized in en-US culture. Please find the following table lists the default keywords and its localized text values for en-US culture.

Locale key words Text
SpellCheckButtonText Spelling
NotInDictionary Not in Dictionary
SuggestionLabel Suggestions
IgnoreOnceButtonText Ignore Once
IgnoreAllButtonText Ignore All
AddToDictionary Add to Dictionary
ChangeButtonText Change
ChangeAllButtonText Change All
CloseButtonText Close
CompletionPopupMessage Spell check is complete
CompletionPopupTitle Spell check
NoSuggestionMessage No suggestions available
NotValidElement Specify the valid control id or class name to spell check

To localize SpellCheck into any particular culture, it is necessary to refer the culture-specific script files in your application after the reference of ej.web.all.min.js file, which are available under the following location.

<Installed location>\Syncfusion\Essential Studio\\JavaScript\assets\scripts\i18n

The following code example shows how to localize the SpellCheck control in fr-FR culture.

  • html
  • <!--Container for ejSpellCheck widget-->
    <div id="SpellCheck"></div>
    <script type="text/javascript">
    $(function() {
        ej.SpellCheck.Locale["fr-FR"] = {
            SpellCheckButtonText: "Vérification orthographique",
            NotInDictionary: "Pas dans le dictionnaire",
            SuggestionLabel: "Suggestions",
            IgnoreOnceButtonText: "Ignorer une fois",
            IgnoreAllButtonText: "Ignorer tout",
            AddToDictionary: "Ajouter au dictionnaire",
            ChangeButtonText: "Changement",
            ChangeAllButtonText: "Tout modifier",
            CloseButtonText: "Fermer",
            CompletionPopupMessage: "Vérification orthographique est terminée",
            ErrorPopupMessage: "Vérification orthographique est pas terminée",
            CompletionPopupTitle: "Vérification orthographique alerte",
            OK: "D'accord",
            NoSuggestionMessage: "Aucune suggestion disponible",
                    dictionarySettings: {
                        dictionaryUrl: "http://js.syncfusion.com/demos/ejservices/api/SpellCheck/CheckWords",
                        customDictionaryUrl: "http://js.syncfusion.com/demos/ejservices/api/SpellCheck/AddToDictionary"


    Refer the ej.culture.fr-FR.min.js file in your HTML application and also define the locale property for the SpellCheck control with the appropriate culture-code [fr-FR].

    For further information on how to refer the required culture scripts into your application, refer here.

    Localizing Specific Words

    To customize or localize only some specific words in the default ej.SpellCheck.Locale["en-US"] collection, the words to be localized/customized can be defined in a separate variable and then extended to the original collection as depicted in the following code example.

  • html
  • <script>
    var customizationMessage = {
        CompletionPopupMessage: "Completed",
    // Extend only the required changes to the original locale collection
    $.extend(ej.SpellCheck.Locale["en-US"], customizationMessage);
    $(function() {
        // defining SpellCheck control
                    dictionarySettings: {
                        dictionaryUrl: "http://js.syncfusion.com/demos/ejservices/api/SpellCheck/CheckWords",
                        customDictionaryUrl: "http://js.syncfusion.com/demos/ejservices/api/SpellCheck/AddToDictionary"
