About XML
XML is a text-based tree format made of elements, attributes, text nodes, namespaces, processing instructions, comments, and optional declarations. It is used when producers need explicit structure, validation, mixed content, or long-lived interchange between systems. XML appears in enterprise feeds, publishing pipelines, invoices, metadata records, SOAP services, vector and ebook subformats, and many government submissions. Our tabular routes convert XML to JSON, JSONL, CSV, TSV, XLSX, ODS, SQL, Parquet, YAML, HTML, Markdown, or TXT when a table-like record set can be derived. FB2 to XML is also enabled for FictionBook sources that already use XML internally.
XML versions and surrounding standards shape conversion. XML 1.0 is by far the common baseline, while XML 1.1 is rare. Namespaces distinguish identical local names from different vocabularies. DTDs, XSD, Relax NG, and Schematron can define validity, but many converters only parse well-formed data and do not validate business rules. Encodings may be declared in the XML prolog, inferred from bytes, or contradicted by transport headers. CDATA sections, entity references, comments, and processing instructions may not survive into JSON or spreadsheets because the target models have no matching concept. Legacy feeds also hide business rules in external schemas.
Readers and writers include Java and .NET services, publishing systems, tax portals, content management systems, office packages, e-commerce feeds, standards bodies, and legacy integration buses. Some XML files are record-oriented, such as repeated product elements under one root. Others are document-oriented, with paragraphs, emphasis, footnotes, and inline tags mixed together. A spreadsheet conversion only fits the first category. Document XML often needs a format-aware converter, stylesheet, or custom extraction rule. Ask whether the recipient wants the full tree, a selected repeated element, or a rendered document view. That distinction controls whether rows can be trusted.
Conversion gotchas come from flattening a tree into rows. Attributes may become columns, child elements may become dotted paths, and repeated child lists may become JSON strings or duplicate rows depending on the extraction strategy. Namespaces can make column names noisy but removing them can create collisions. XML to JSON preserves hierarchy better than XML to CSV, but still changes attributes and text-node ordering. XML to XLSX is useful for inspection when the XML is a feed. Before conversion, identify the repeating record element, preserve a sample with namespaces intact, and compare item counts after export.
Common XML problems
Namespace prefixes make output columns unreadable.
Use /convert/xml-to-json first to inspect the tree, then rename columns after confirming prefixes do not distinguish real fields.
A mixed-content document becomes fragmented cells.
Use /convert/xml-to-html or keep the source XML; /convert/xml-to-csv is meant for repeated records, not prose markup.
Attributes disappear when someone copies rows manually.
Use /convert/xml-to-xlsx so attributes and child values are materialized consistently for review.
The receiving API wants XML but the export is JSON.
Use /convert/json-to-xml, then inspect array element names because JSON has no native root element convention.
A database import needs rows, not a nested tree.
Use /convert/xml-to-sql only after selecting a record-shaped XML feed and checking repeated child counts.
