Paste YAML into the editor or load a basic, Kubernetes, Docker Compose, or CI/CD example. Change a value and inspect syntax validation before exporting it. Select the indentation you want and press Format for the current document. In the example below, the edited replica count remains a number. Use the download menu to choose the current document or all documents when you have several document tabs.
Formatting serializes parsed data and can remove comments, so keep the original when annotations matter. Syntax validation does not check the deployment rules of Kubernetes or another consumer. The editor offers two, four, or eight spaces for formatting; choose the convention used by the surrounding project. Reopen your downloaded file to confirm you exported the intended document rather than another tab in the same editing session.
Input: replicas: 1
Edit and format:
replicas: 2
Edit YAML in tabs with syntax validation, formatting, templates, and YAML downloads. Text editing with line numbers, document tabs, and YAML file upload and download.
The editor parses YAML as you change it and reports syntax errors. A successful parse does not establish Kubernetes, Docker Compose, or CI schema correctness. Check those rules in the consuming system. When Format rewrites a document, comments and scalar presentation may change, so keep the original if annotations or exact spelling matter.
The editor is essential for Configuration Management (application configurations, environment settings, system parameters), DevOps Workflows (Kubernetes manifests, Docker Compose files, CI/CD pipeline configurations), Infrastructure as Code (cloud infrastructure templates, deployment configurations, service definitions), Data Processing (data pipeline configurations, ETL job definitions, workflow orchestration), and Development Tasks (API documentation, configuration management, microservices setup, testing configurations).
Each document tab keeps its own content and syntax-validation results. Download the current document or combine all tabs into a YAML file.
Use Format to serialize the current document with 2, 4, or 8-space indentation. Formatting may remove comments.
Text editing with line numbers, document tabs, and YAML file upload and download.
Real-time syntax validation with instant error detection and reporting.
Use Format to serialize the current document with 2, 4, or 8-space indentation. Formatting may remove comments.
Upload files, auto-detect multi-document YAML, and download individual or combined documents.
Download the current document or combine all tabs into a YAML file.
Editing and validation run in your browser. Sharing or saving to the library sends the content you choose.
