I want to move some text from column B, C and D to the end of the text in Column A.

For example:

From
Column A Column B Column C Column D
158 Happy Rd Happy Valley Happy City USA

To
Column A Column B Column C Column D
158 Happy Rd Happy Valley Happy City USA

All text will be moved to the column A.

Is there any shortcut to do that? I have about 100 rows to perform this.

Thanks.
