# WebViewer Localization

Explore setting the ActiveReports WebViewer UI language and personalizing the language.

## Content



This article discusses setting the WebViewer UI language.

The localization file for [WebViewer](/activereportsnet/docs/v20.1/developers/create-applications/aspnet-webviewer-application) is **ar-webviewer-locale.json**. This file is automatically added to the project in the **grapecity.activereports.web\\content** folder when you install the [MESCIUS.ActiveReports.Web](https://www.nuget.org/packages/MESCIUS.ActiveReports.Web/) NuGet package, which is required when using WebViewer. The 'ar-webviewer-locale.json' file contains English localization so that the user can use it as a template for their own localization.

To localize WebViewer, first translate all the resources in the 'ar-webviewer-locale.json' file. Once you have translated all the resources, you must specify the location of the 'ar-webviewer-locale.json' file in the WebViewer’s [LocalizationJson](/activereportsnet/api/v20.1/MESCIUS.ActiveReports.Web/GrapeCity.ActiveReports.Web.WebViewer.html) property.

```csharp
WebViewer1.LocalizationJson = File.ReadAllText(Server.MapPath("~") + " ar-webviewer-locale.json ");
```
