Compare upper, lower, proper and preserved text
Your goal: Compare three capitalization methods beside the untouched source, reveal case-sensitive changes and choose a policy explicitly.
Full task requirements
Fill C2:G5 as twenty separate formulas. C uses UPPER, D LOWER and E PROPER on the same original row. F compares the original to E using EXACT. G uses CHOOSE and numeric B7: 1 selects C, 2 D, 3 E and 4 the untouched original B value. B2:B5 must be nonempty printable ASCII text up to 40 characters, including spaces, punctuation and numeric-looking spelling. Preserve all spaces and characters outside letter case. B7 is a numeric whole policy index 1..4. This bounded mechanical case comparison is not a name-correction service, title-style guide or multilingual capitalization certification.

Rules for this step
Select the original text, preserve every space and punctuation mark, and apply the stated mechanical case policy. PROPER capitalizes a letter after any nonletter; it is not a name-correction rule.
