Arelle

Arelle specializes in standards-based financial reporting technology, centering on an end-to-end open-source XBRL platform that streamlines the creation, validation, and analysis of structured business data. The software serves regulators, accountants, auditors, and analysts who must prepare, review, or consume filings in XBRL and Inline XBRL formats, turning dense regulatory documents into machine-readable reports that can be automatically checked for taxonomy compliance, mathematical consistency, and disclosure completeness. Typical use cases include SEC and ESMA filings, European Single Electronic Format (ESEF) annual reports, and global data collection projects that demand traceable, version-controlled metadata. Command-line, web-service, and graphical interfaces allow batch processing of thousands of filings or interactive exploration of individual documents, while built-in visualization tools highlight calculation networks, dimensional cubes, and extension taxonomies. Because the codebase is open, agencies and firms can embed the engine into portals, workflow systems, or continuous-integration pipelines, customizing validation rules and output formats without licensing fees. Arelle’s software is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always installing the latest version and supporting batch installation alongside other applications.
