Structured data rarely arrives in the format you need it. A config file wants YAML, an API returns JSON, a client sends a spreadsheet as CSV, and a legacy integration still speaks XML. These converters move data between those formats without a round trip to a server — the parsing and serialising happen in your browser, so a file containing credentials or customer records never leaves your machine.
