The Text Manager will make working with text in your spreadsheet very easy. It is particularly useful for text which has been imported into Excel. You specify the range to affect, this can be specified cells or the entire sheet.
The Change Case lets you instantly change the case of your text. You can nominate to change your text to:

upper case

lower case

proper case.

The Remove Character or Text can save you many hours of manually removing specific characters, or text, from specified text. You can even copy the characters to remove directly from the Windows Character Map. If the character or text you wish to remove is not available, simply check the Specify Character or Text option.

Numbers not being seen as true numbers.

Dates not being seen as true dates.

Hard or impossible to break up text.

Hard or impossible to reference text.

Hard or impossible to use text in formulas.

You can remove all:

Leading spaces

Trailing spaces

Trailing and Leading spaces

All spaces, except for single spaces between words.

Have some text you wish to concatenate (link together)? The Text Manager can do this is quickly and easily. Simply specify the cells to concatenate, then specify the cell to concatenate the text into and click OK. Your text will instantly be joined. You can also tell the Text Manager to add a space between each cell that is joined.
