Validate all unit expressions in a CSV file

We can validate unit expressions in a comma separated values file on your system.

  • Use the browse button below to select the file.
  • You will then be asked for the name of the column that contains the expressions to be validated. (Your file must include column headers).
  • A copy of your file will be created that includes three additional columns at the end, confirming what expression was validated, the validation results, and any relevant notes.
  • You will be asked where you want the file saved. You may change the name of the output file at that time.
  • Note that this will only validate unit expressions. Although prefixes used with a unit code, e.g., "kL" (kiloliter), are recognized as prefixes ("k" for kilo) modifying a unit code ("L" for liter), a prefix submitted by itself, e.g., "E" (exa) will result in an "invalid unit code" return.
