How It Works

Simple by Design

Send your data in any format, specify the target format, get back the result. No schemas. No configuration. No SDKs required.

Send Your Data

POST your raw data to /api/convert with source and target format specified. Supports up to 10 MB per request.

Instant Conversion

The engine detects the format, parses the structure, normalizes records, and serializes to your target. Binary documents are extracted automatically.

Get the Result

Receive clean, properly encoded output. Errors return structured messages — never raw stack traces. All responses include format metadata.

★

Or Use It as an MCP Tool

Connect Claude, Cursor, or any MCP-compatible AI agent directly. The service exposes 5 tools via the Model Context Protocol — no API calls needed from the agent side.

Use Cases

Built for Real Workloads

🤖

AI Agent Pipelines

Connect Claude, GPT-4, or any MCP-compatible agent. They can call convertData directly as a tool — no extra API calls, no prompt engineering needed to parse formats.

🔌

API Integrations

Bridge incompatible APIs without writing parsers. Receive XML from a legacy system, convert to JSON for your frontend, reshape fields with dot-notation — in one request.

📄

Document Processing

Extract structured data from PDF reports, Excel spreadsheets, and DOCX files. Convert to any text format for downstream analysis or storage.

🔄

ETL Pipelines

Use the batch endpoint to process up to 50 files in a single request. Mix formats freely — CSV inputs alongside YAML configs, all converted in one shot.

🛠️

Developer Tooling

Embed in CLI tools, VS Code extensions, or CI pipelines. Convert configs between YAML and TOML, generate Markdown tables from JSON, serialize test fixtures.

🔐

Security-Sensitive Workloads

XXE protection, formula injection prevention, input size limits, and 30+ security tests. Safe to use with untrusted user data in production.
