Developer Data Utility Suite
Five mission-critical tools crafted for backend engineers, frontend developers, and data practitioners. Every transformation executes locally inside your browser sandbox with syntax highlighting, exact line error reporting, and one-click exports.
JSON Formatter & Validator
Pretty-print, minify, sort keys, unescape strings, and pinpoint syntax errors with exact line and column locations.
JSON to CSV Converter
Transform complex JSON arrays and nested object hierarchies into clean, RFC 4180 compliant CSV tables with custom delimiters.
CSV to JSON Converter
Parse standard CSV documents and TSV tables into clean, typed JSON objects with automatic delimiter detection and type inference.
Merge Multiple JSON Files
Combine multiple configuration files, environment overrides, or split datasets with recursive deep merge and prototype pollution protection.
XML to JSON Converter
Convert RSS feeds, SOAP envelopes, SVG, and legacy enterprise XML payloads into modern structured JSON with attribute and CDATA support.
Why Engineers Trust DataTools for Sensitive Payloads
Unlike generic online converters that POST customer data, API keys, or financial logs to backend analytics queues, DataTools operates completely client-side in your local browser sandbox. Unplug your internet connection: every tool continues working without interruption.
