By using structured spreadsheets, teams can ensure that data requirements are consistent across different software platforms.

Developed by buildingSMART , IDS is an XML-based standard used to define "information requirements" within a BIM project. It specifies exactly what data (like material type or fire rating) must be present in a digital building model at different stages of construction.

Automated scripts can compare a digital building model against the requirements defined in an IDS file, instantly flagging missing or incorrect information.

While the primary use is in construction (BIM), variations of "idsxls" appear in other technical fields: Free Keyword Research Automation Spreadsheet

Because XML files are difficult for most professionals to read or edit directly, teams use Excel (XLSX) files as a user-friendly interface.
