Format Details
FWF
FWF (Fixed-Width Format) is a plain-text data format where each column occupies a predetermined number of character positions in every row, with no delimiter characters between fields. It originated on mainframes and is still common in government data releases, financial industry feeds, and legacy enterprise system exports. FWF files require a separate schema or data dictionary to correctly parse the column boundaries, making them less self-describing than CSV.
XML
XML (eXtensible Markup Language) is a flexible, human-readable markup language defined by the W3C for structuring, storing, and transporting data across different systems. Unlike HTML, XML uses custom-defined tags chosen by the author to describe the semantic meaning of data, making it self-documenting and extensible. XML underpins numerous data formats, web services (SOAP), configuration standards, and document formats including SVG, DOCX, and RSS.
