How do I create new cell styles that can be used in other spreadsheets?

I’ve created some cell styles in a spreadsheet and I want to use these styles in other spreadsheets already created and in future spreadsheets.

How can i do this? Or at least, how can i load other cells styles without creating them again?

Note: The goal is to use these styles in conditional formatting

Simply copy cells having assigned the wanted styles from the source sheet and paste into the target sheet.
If the chosen style names aren’t already used by the target document, the new styles will be imported.

Predefined styles having the same names are not overwritten. The pasted cells get assigned the locally applicable styles of the chosen names instead. Direct attributes survive.

Great, it was easier than I thought. Thanks :slight_smile:
