[[Save file: /tmp/errors_2017-04-25_1493102119_excel.xlsx]]
Validation errors store in: [[/tmp/errors_2017-04-25_1493102119_excel.xlsx]]

/PATH/excel_validator>pause
Press any key to continue . . .

Script will create new Excel file with marked errors (red background for invalid cells). If --errors=true option is set, script will also print validator message in invalid cells. Example file with errors errors_2017-04-25_1493102119_excel.xlsx is attached to repository in example directory.

Windows user bonus

validate.bat contains example usage (same as in this documentation) of script. In Windows you can Drag & Drop Excel file on validate.bat script and it should execute validation. Of course you should change content of this file according to your needs.

NOTE

This script should not change original Excel file. Of course it is always good to have and work on copy :)

Changes to script

You can do whatever you want & need with this script. I will be more than happy if it will be useful for you and you will make it better.
