Localization String Catalog Editor is a multi-format software localization workbench for editing, validating, and converting application translation catalogs on Linux. Designed as an independent Linux desktop alternative to ResXManager and translation table editors, it supports side-by-side source and target string editing across major localization file formats.

Key Features:

• Multi-Format Catalog Support: Opens, edits, converts, and losslessly saves .NET XML resource files (.resx), GNU Gettext catalogs (.po / .pot and compiled .mo import), Qt Linguist translation files (.ts), and nested or flat JSON locale files (.json).
• Side-by-Side Translation Table & Inspector: Displays keys, contexts, source strings, editable target translations, translator comments, and review states with instant search and status filtering.
• Format Placeholder & QA Validator: Checks every catalog entry for untranslated keys, fuzzy or unfinished markers, and format token mismatches across printf (%s, %d, %1$s), brace ({0}, {name}), and Qt (%1, %2) placeholders.
• Locale Completion Chart & Reports: Renders per-locale translation completion charts and exports structured CSV reports for localization review workflows.
