Why use an online editor
Translation editor vs. manual file editing
Editing raw JSON or YAML files by hand leads to syntax errors, merge conflicts, and broken builds. A dedicated editor eliminates these risks.
File format support
Edit any translation format
Import and export JSON, YAML, XLIFF, PO/POT, ARB (Flutter), Android XML, iOS Strings, Java Properties, PHP, CSV, Excel, and 20+ more formats. The editor normalizes everything internally: import in one format, export in another.
Use namespaces to manage translations for a React frontend (JSON), an Android app (XML), and an iOS app (Strings) all in the same project.
Pro tip: Keyboard shortcuts for power users
Navigate and edit translations without touching the mouse. The editor supports keyboard shortcuts for the most common actions.
Better translations with context
Context for translators and AI
Accurate translations require context. The editor lets you attach descriptions, screenshots, tags, and namespaces to every key, so translators and AI engines always understand where and how a string is used.
Context is also passed to auto-translation providers. Set project-level context for DeepL, custom system prompts for OpenAI and other AI engines, and per-language instructions for tone and formality. The result? More accurate AI translations that fit your project perfectly.
Key descriptions
Add notes for translators explaining where and how a string appears in the UI.
Screenshots
Attach screenshots to keys so translators see the exact UI context. OCR auto-matches keys.
AI context
Project context, language-specific tone, and custom system prompts for AI auto-translation.
Tags & namespaces
Organize keys by feature, module, or category. Filter, assign permissions, and export by group.

What is an online translation editor?
An online translation editor is a web-based tool for editing translation files used in software projects. Instead of modifying raw JSON, YAML, or PO files in a code editor — risking syntax errors, merge conflicts, and broken builds — teams use a dedicated translation editor to manage all their localized strings in a structured, visual interface.
The SimpleLocalize translation editor is the core editing experience of the SimpleLocalize TMS. It supports 30+ file formats, built-in AI auto-translation, translation memory, a QA checks system, and a collaborative review process — all accessible from your browser.
Supported file formats: JSON, YAML, XLIFF, ARB, and more
The editor supports JSON (single and multi-language), YAML, XLIFF, PO/POT, ARB (Flutter), Android XML, iOS Strings, Java Properties, PHP arrays, CSV, Excel, and many more. Import in one format and export in another. Use namespaces to organize translations by module, feature, or platform.
How translation memory improves editing speed
Translation memory stores every translation you save. When a new source string is similar to a previously translated one, the editor suggests the existing translation — saving time and maintaining consistent terminology across your project. Memory spans all languages and namespaces, so work in one area benefits the entire codebase.
Review process and team collaboration
The editor includes a built-in review process. Translators submit their work, reviewers mark translations as approved or flag issues, and project managers track overall progress with status filters and statistics. Tasks help coordinate who works on what. Comments on individual keys reduce back-and-forth, and role-based access ensures everyone sees only what they need.
