A lightweight desktop editor that lets you view, edit, and validate JSON localization strings without touching spreadsheets.

Why I Built It

I wanted a first hands-on project with Avalonia UI and MVVM. Managing localisation files is a real-world pain point, so the app focuses on fast iteration and clear validation.

Core Capabilities

• Load any JSON file that follows the LocalizedStrings schema
• Inspect keys, default text, and all language translations
• Add / remove languages or entire entries on the fly
• Save back to JSON with a single click

Tech Stack

C# · .NET 6 · Avalonia UI · System.Text.Json · MVVM

Next Up

• Prompt on unsaved changes
• Undo / redo that covers all operations
• Inline fold-out editor instead of a dedicated side panel
