Before exporting, you may want to clear your cache in Chrome to reduce the size of the profile. Close all Chrome windows before continuing. Press "Windows-R," type or paste "%LOCALAPPDATA%\Google\Chrome\User Data\" (without quotes) into the Run window and press "Enter." Using the right mouse button, drag the "Default" folder onto your desktop, a USB drive or wherever else you want to save the profile and pick "Copy Here."
To use your exported profile, close any Chrome windows and move your "Default" folder copy into %LOCALAPPDATA%\Google\Chrome\User Data\ on any computer with Chrome installed. This will overwrite the existing profile unless you move or rename the existing "Default" folder first. If you're moving to a new computer, you need to install Chrome before restoring the folder.
