How to Split Excel Spread Sheet:
It can
be difficult working with long Microsoft Excel spreadsheet documents and
knowing what row or column you're
working in when scrolled past the top row or far left column. To keep a row or
column locked in place split the spreadsheet by moving the mouse cursor over
the icon above the right scrollbar or to
the right of the bottom scrollbar. Once positioned correctly your mouse cursor
will turn into a double-arrowed cursor as shown in the picture. Hold down your
mouse and drag down or to the right until the document is split where needed.
How
do I unsplit?
If you
want to remove this click-and-drag the split line back up to the top or far
right of the spreadsheet until it vanishes and let go of the mouse button.
