I have just had to place a textbox object onto 17 worksheets within the same excel workbook, each text box containing the same commentary text. Type it once and then copy the text box and paste, job done.
Of course as soon as I have finished it I spot my typo and realise I will have to do it all again.
Only NOW do I slow down and think (OK I Google it) of the proper way to do it.
When you create a text box, rather than typing the text into the text box as I have been doing for years, with the text box selected you can type into the formula bar. In my case I put in the formula “=Metadata!B2″. This means that the textbox will display whatever I type into cell B2 on my “Metadata” worksheet.
Now I edit the textboxes I have created to reference the formula and in the future if the text needs to change, I change it in Metadata!B2 and the new text appears in all of the textboxes that refer to it!
NOTE: The text displayed in a formula driven text box is limited to 256 characters.
