Data Conversion Tools

Data conversion is one of the most repetitive tasks in development and data analysis. Converting an API's JSON response to CSV for spreadsheet import, transforming a configuration file from YAML to JSON to validate against a schema, encoding a binary file to Base64 for embedding in a JSON payload, converting a Markdown README to HTML for a CMS — these are everyday tasks that shouldn't require writing a script or installing a library. The JSON to CSV, JSON to YAML, and Markdown to HTML converters handle these format translations instantly, with no installation required.

The encoding tools cover the most common encoding challenges. The Base64 Codec handles text and file encoding for API payloads, data URIs, and authentication headers. The URL Encoder/Decoder handles percent-encoding for query strings and path components. The HTML Entity Decoder and Unicode Converter handle the character encoding questions that come up when working with international text, scraped HTML, or data that has passed through multiple systems.

The unit conversion pages go beyond simple number conversion. Each page shows the formula, works through the calculation step by step, and includes a quick-reference table of related conversions in the same category. Temperature, length, weight, volume, speed, area, digital storage, time, energy, and pressure are all covered, with individual pages for hundreds of specific conversion queries — from cooking temperatures and marathon distances to cloud storage capacities and tire pressure.
