The final sheets with selected data are all CSV and one also in Excel. The colums all have headers with the common symbols and units in geotechnical emngineering
The source data is placed in the location folders under 2018 (only unit weight) and 2021 (all labtest data) database.
The CPTs are all in the standarized GEF format.
