About the formats

What is XLSX?

XLSX (Excel Open XML) is the standard spreadsheet format from Microsoft Excel, also supported by Google Sheets and LibreOffice Calc. Data is organised into cells and sheets, with support for formulas, functions, charts and formatting. Because the file is a ZIP container of XML, its content stays readable and easy to process.

Use XLSX for tabular data that needs structure and calculation, budgets, inventories, lists and anything with formulas or multiple sheets. When you only need the raw data, you can export a single sheet to CSV or JSON here.

What is XML?

XML (Extensible Markup Language) is a W3C standard for describing structured data as text, using nested tags that you define yourself. It is both human-readable and machine-readable, and supports schemas to validate documents. Many other formats are built on XML, including SVG, RSS feeds and the internals of DOCX and XLSX files.

Use XML when a system, API or industry standard requires it, such as electronic invoices, sitemaps, feeds or configuration files, or when you need strict validation with a schema. For lightweight data exchange between web applications, JSON is usually more compact.
