Data Converter APIs: Transform Formats Without the Headaches

Data format conversion sounds simple until you deal with edge cases — nested JSON to flat CSV, timezone-aware date conversion, or color space transformations. Converter APIs handle these transformations reliably, with proper error handling for malformed input and consistent output formatting.

Why use a converter API?

Convert between JSON, CSV, XML, and YAML without format-specific parsing libraries
Generate PDFs from HTML with pixel-perfect rendering via headless Chrome
Handle timezone conversions correctly, including DST transitions and edge cases
Transform color values between HEX, RGB, HSL, HSV, and CMYK with precision
Convert units of measurement for international applications without lookup tables

How to convert data with Van Moose

Identify source and target formats

Data Converter for JSON/CSV/XML/YAML, PDF Generate for HTML to PDF, Color Converter for color spaces, Unit Converter for measurements, Timezone API for time conversion.

Send your input data

POST the source data to the appropriate API endpoint. Specify the target format and any conversion options (delimiters, precision, timezone identifiers).

Use the converted output

The API returns the converted data in the requested format. For binary outputs (PDF), the response is a downloadable file. For text formats, the response is a JSON wrapper with the converted content.

Quick example

PDF Generate API

curl -X GET \
  "https://pdfgenerate.vanmoose.cc" \
  -H "Authorization: Bearer vm_live_YOUR_API_KEY"

Replace vm_live_YOUR_API_KEY with your actual API key from the dashboard.

Frequently asked questions

Can I convert JSON to CSV with nested objects?+

Yes. The Data Converter API flattens nested JSON objects using dot notation for column headers. Arrays are expanded into separate rows. You can customize the delimiter, quote character, and header format.

How does PDF generation work?+

The PDF Generate API renders HTML using headless Chrome, producing pixel-perfect PDFs. You can pass raw HTML or a URL. Supports custom page sizes, margins, headers/footers, and background graphics.

Does the Timezone API handle daylight saving time?+

Yes. The Timezone API uses the IANA timezone database and correctly handles DST transitions. It returns the current UTC offset, DST status, and the next transition date for any timezone.

What color spaces are supported?+

The Color Converter API converts between HEX, RGB, HSL, HSV, and CMYK. It also returns color names (when available), contrast ratios against black and white, and complementary colors.
