Import ASCII File (single row format)
The Import ASCII File (single row format) command is usually used to import standards into a new standard database from an Excel spreadsheet that has been saved as a tab delimited text file with a .DAT extension. Each standard must be on a single row with a separate column (H to Fm) for each element weight percent, number of cations and number of oxygens (for oxide formulas).
See the format of a test file produced by the Export ASCII File (single row format) menu.
