XT Viewer Online

XT Viewer Online provides a client-side data viewer that renders nested structures from common data formats into a readable, tree-like representation. It targets developers, data engineers, testers, QA analysts, and technical consultants who need a quick sanity check of payloads, configuration files, or sample data without installing tools.
Inputs are accepted as plain text or pasted snippets. The tool detects the data type (JSON, XML, YAML, CSV) using lightweight parsers, builds a hierarchical model, and displays an interactive outline with expandable nodes. It preserves the original formatting for reference while highlighting syntax errors and invalid values. Outputs include a standardized, indented view and a compact serialized preview for copy-paste workflows.
Mechanically, the viewer parses input into a tree, records parent-child relationships, and preserves original key names for fidelity. It supports optional type hints to annotate inferred data types and can perform shallow comparisons to spot structural differences between payloads. Core features include multi-format support, strict validation modes, and export of the parsed tree in JSON. The tool emphasizes deterministic parsing, stable representations, and non-destructive visualization to support auditing and debugging during integration tasks. Use cases cover API response inspection, configuration validation, payload debugging, data quality checks, and version drift detection in development and testing pipelines.
Unique value derives from browser-based, dependency-free parsing with immediate visual feedback, offline operation, and simple exports for downstream tooling. This combination helps teams accelerate debugging cycles and reduce context-switching during data integration and testing.
