Data Converter Online - JSON, CSV, XML, YAML, SQL & Excel

What is the Universal Data Converter?

iTools Data Converter is an all-in-one data serialization and transformation utility designed for software engineers, database administrators, data scientists, and analysts. In modern distributed systems, data frequently transitions between REST APIs, document datastores, relational SQL databases, message queues, and spreadsheet reports. Our platform provides instantaneous, bidirectionally consistent conversions across JSON, CSV, XML, YAML, TSV, SQL Insert Statements, and Excel (XLSX) with comprehensive syntax validation and schema normalization.

Supported Data Formats & Interoperability Matrix

• JSON (JavaScript Object Notation): Native web serialization standard. Supports minification, 2/4-space beautification, JSON Schema validation, and nested array parsing.
• CSV & TSV (Delimiter-Separated Values): Auto-detects delimiters (comma, tab, semicolon, pipe), sanitizes multi-line quoted strings, and handles UTF-8 BOM encoding smoothly.
• XML (Extensible Markup Language): Converts complex hierarchies to and from attribute-centric or node-centric schemas, with automated CDATA wrapping and namespace support.
• YAML (YAML Ain't Markup Language): Ideal for Kubernetes manifests, Docker Compose configs, and CI/CD pipeline authoring. Ensures indentation integrity and scalar typing.
• SQL INSERT & CREATE TABLE: Automatically inspects records, infers database column types (VARCHAR, INTEGER, TIMESTAMP, BOOLEAN), and generates sanitized SQL DDL & DML statements.

Advanced Capabilities: Array Flattening & Schema Inference

• Nested JSON Flattening: Convert deep multi-level object trees into flat tabular rows using standard dot-notation (user.address.city) or custom bracket conventions.
• Live Error Highlighting: Visual line-by-line syntax diagnostics report exact column and token discrepancies before transformation occurs.
• Bidirectional 1-Click Swap: Invert source and target with a single click (e.g., flip from JSON-to-CSV to CSV-to-JSON) retaining existing inputs.
• Instant Copy & File Export: Download sanitized output as .json, .csv, .xml, .yaml, or .sql, or copy directly to your clipboard.

100% Client-Side Confidentiality

Enterprise payloads frequently contain customer records, internal UUIDs, API keys, and sensitive financial logs. iTools processes every conversion entirely within client-side Web Workers. Your data is never transmitted over the internet or logged in server telemetry, satisfying stringent enterprise data governance requirements.
