It's easier to paste your resume into the Resume text box, if the resume has been saved as plain text. To do so:
Open your resume in a word processor or text editor.
From the File menu of the word processor, select Save As. The Save As dialog box will open.
From the Save As Type drop-down menu (located at the bottom of the Save As dialog box) select Text Document or Text Only.
Now that you have a plain text version of your resume, it will be easy to copy and paste your resume into the Resume text box. Next, see Enter Your Resume Into the Resume Text Box.
