' GridAll_loop sheets.bas grids all of the worksheets in a selected Excel file ' Grid files are saved in the same directory as the Excel file and named according to the sheet name.

'b) "xMin must be < xMax" usually means there is no griddable data. Check if there really is data, if it is in columns ABC, and that it is formatted as number and not as text or general. 'c) "Insufficient data in worksheet" means there are less than three griddable Z values in the worksheet. 'd) "Inadequate data (all data lie in a horizontal plane)" means that all Z values are the same. 'e) "Unknown worksheet import format" the file format was incompatible with Surfer. Common if the file was an Excel 2007 spreadsheet and your Surfer version is 8 or lower.
