Features

Spreadsheet-style grid: keys × languages
File tree with checkboxes to scope which .resx families appear
Choose which language columns to show; Summary always lists every locale
Fast in-memory search/filter
Validation rules (PascalCase keys, matching string endings, placeholders, missing translations)
Warnings in the grid, Summary, and VS Code Problems panel
Auto-update *.Designer.cs when keys change
Import/export Excel (.xlsx / .xls) for the selected families
Extension UI in English and Portuguese

Usage

Open a workspace that contains .resx files
Run ResX Guard: Open from the command palette, or use the Activity Bar icon
Select resource families on the left, edit translations in the grid
Use Export / Import in the toolbar to round-trip the selected families through Excel (.xlsx / .xls). Empty cells on import leave existing translations unchanged.

Settings

See ResX Guard in VS Code Settings for key naming, Designer.cs generation, and validation rules.
