XBRL (Extensible Business Reporting Language) is a standardized way for companies in India to electronically file their financial statements with regulatory authorities like RBI, MCA, SEBI, and IRDA. It enhances the accuracy, comparability, and transparency of financial reporting while allowing for customizability to meet organizational needs. Companies listed on stock exchanges, with significant paid-up capital or turnover, are required to file in XBRL format, and various tools and software are available to facilitate this process.
