The HEC-DSS Excel Data Exchange Add-In is a Visual Basic Application for retrieving and storing both regular-interval time series and paired data directly from Excel to an HEC-DSS database file. Data sets to retrieve are selected from a catalog listing directly available from Excel. For time series data, an optional time window can be specified to select portions of a DSS record or to span several records. The exchange of irregular-interval time series data has not been implemented at this time.

The HEC-DSS Excel Data Exchange Add-In is a separate capability from the HEC-DSSVue Excel Plug-in. The HEC-DSSVue Excel plug-in is run from HEC-DSSVue and can read and write both regular and irregular-interval time series data, but has not been implemented for paired data. The HEC-DSS Excel add-in is run from within Excel. While the format of the data is more restrictive, it can read and write both regular interval time series data and paired data, but not irregular-interval time series data.
