What is it

CSV describes tabular data with comma separators; XML describes structured data with nested tags. This tool parses your CSV into an object array with PapaParse, turns the header row into XML tag names, and uses fast-xml-parser XMLBuilder to wrap each record as a row element under rows, so the output is always a well-formed XML document.

Notes & fun facts

CSV is the simplest tabular data format; XML is the most rigorous markup language. When you need to feed Excel-exported CSV data into enterprise systems, generate SOAP envelopes, build RSS feeds, or construct request bodies for legacy web services, you need to convert CSV to XML. This tool does it locally in your browser: PapaParse parses the CSV, the header row becomes XML tag names, numbers and booleans are auto-detected, and fast-xml-parser XMLBuilder wraps each record as a row element under rows. No file upload, no plugin, paste and convert, copy straight into your code.

Origin & history

CSV has been in use since mainframe times in the 1960s as the plainest cross-system data format. XML 1.0 was published by the W3C in 1998 as a simplified subset of SGML and became the de facto standard for enterprise data exchange throughout the 2000s. PapaParse is an MIT-licensed CSV parser open-sourced in 2013, and fast-xml-parser is an MIT-licensed XML builder/parser open-sourced in 2018; both are zero-dependency and browser-friendly.
