TMXEditor is a cross-platform, open-source TMX editor for macOS, Linux, and Windows.

Translation memories accumulate encoding errors, invalid entries, and duplicates over time, and often grow too large or too multilingual for most CAT tools to open, clean, or validate reliably.

Why TMXEditor

• Processes TMX as a standards-based XML format, validated against the official TMX specification, rather than as an opaque CAT-tool database.
• Handles very large, multilingual translation memories without being limited to a single source/target language pair.
• Converts between TMX and the formats you already work with, including Excel, CSV, SDLTM, and TBX.
• Open source and cross-platform, built on the same TMX validation technology as TMXValidator.
