Remove "embedded" format & Ctrl icons residues?

[Bebbspoke]

Hi Peoples - pls - when a large & commonly used file is opened or saved it is observed that there may be several Format &/or Control icons present which (I assume) are residual from not being fully applied or cancelled during the use of the worksheet...

I'm convinced that these slow the overall processing...

so please, how may such be idenetified and cancelled?

Thank you
