XBRL (eXtensible Business Reporting Language) is an open standard for digital business reporting that allows for accurate, automated exchange of business and financial data. It provides a standardized language and taxonomy to define financial terms, allowing investors and stakeholders to easily access and understand financial reports. While XBRL is not universally adopted, it is spreading globally and facilitates more efficient reporting while reducing costs for companies and regulators. Some disadvantages remain around inconsistent implementation and potential errors in assigning tags, but overall XBRL aims to increase transparency and comparability of financial information.
