A method to prepare an Extensible Business Reporting Language (XBRL) document in a web-hosted server includes authenticating a user, uploading financial information from a spreadsheet, storing the information, and processing the data into an XBRL compliant document for transmittal to a financial regulatory agency. The process takes an input from an Excel™ spreadsheet and produces a financial statement in XBRL format while providing a full audit trail for the document conversion and authorization including manual inputs to the final-form submission.
