Numbers on MacOS: Set language to US English?
I live in the UK, but I need my Numbers sheet to use US English spellings.
I've tried everything, but the inline spelling seems to check everything as UK English, so any US spellings get flagged up as errors, which makes proofing my work harder than it should be.
How can I force Numbers to only use US English spellings for the inline spell checker?
Steps I have tried:
1. Going to Apple menu > System Preferences > Language & Region
I have deleted all languages other than US English and Japanese. The region is set to UK, because I prefer UK units:
2. In Numbers I have gone to File > Advanced > Language and Region:
For Language, it only gives me the option of English (There is no US English option). However, I have set the region to US.
Any ideas?
