1.Toolbox t configuration  exported Excel file format is a  xlsx  flie , but with xls extension.

2.Toolbox configuration can't import the excel file.

The Excel.exe is  running in the background,but  data cannot be imported.

3.Toolbox configuration custom properties, generate an actual part of the time, was not added to the user in the configuration properties, leading to incompetence.

Question 2, very serious, in 2011, you can use Excel to edit the part number and description, you can use Excel formulas automatically generated, once importedfrom Excel, but by 2012, cannot be used.
