For example) Excel A=250~500,   B= [ 1, 2, 3, 4, 5] A=100~250,   B= [ 1, 3, 5, 7, 9] A=0~100,   B= [ 0, 1, 2, 3, 4] If I need to import these data to Math-cad S/W acorroding to 'A' data variation How can I do? I sincerly need to help. Thank you for reading my question

I presume by "S/W" you mean "software"?  Do you know which version of Mathcad you intend to use (do use?)? There are two major families of Mathcad: Mathcad Prime (the latest version being Prime 3.1) and the older non-Prime Mathcad (Mathcad 15 being the latest version). 

There are several ways to import Excel data into Mathcad.  The READEXCEL function is probably the most versatile.   Many people find the Excel component to be the most convenient, though.

In your example, are both A and B in Excel?  Do you calculate B from A within Excel? Are the 3 ranges in different Excel workbooks or worksheets or are they all on the same worksheet?  Could you post a example workbook(s) to give a clearer idea of what you want?

If you want to select the B data given A's value, then you may find it easier to import all of B from Excel and then select the values you want from the A values.  For example, (assuming you have read B in from the Excel file):

There are also a problem with the international specification. You can see that seven is paste as number, but others as string. You can change the decimal comma by a dot somewhere in windows settings, in "international settings" (not in excel), and try again to copy and paste.
