The Name Fixer cleans up inconsistent capitalization in your spreadsheet, such as names typed in
ALL CAPS (JANE SMITH) or all lowercase (jane smith), so they read
Jane Smith.
First Name, Last Name). Upper/lower case and extra spaces in the column names don't matter.Source Sheet column shows where each row came from.| Style | How It Works | Before | After |
|---|---|---|---|
| Proper Name | Lowercases everything, then capitalizes the first letter of each word and any letter that follows a non-letter such as a hyphen, apostrophe, period or parenthesis. Also capitalizes the letter after a leading 'Mc' and keeps Roman-numeral suffixes (II-X) fully uppercase. | MARY-KATE O'BRIEN MCDONALD III |

| Simple Title Case | Capitalizes the first letter of each space-separated word and lowercases the rest. No special handling for hyphens, apostrophes or prefixes. | MARY-KATE O'BRIEN |

With this option on (the default), a value is only changed if every letter in it is uppercase or every letter
is lowercase. Names that already mix upper and lower case, like DeAndre, MacKenzie
or van der Berg, were probably typed correctly and are left alone. Turn it off to re-capitalize every value.
Some names can't be fixed reliably from all-caps text: MACDONALD becomes Macdonald,
DE LA CRUZ becomes De La Cruz, and DEANDRE becomes Deandre.

🔒 Privacy First: Your data is never stored. Files are processed in memory and immediately deleted after conversion.
⚠️ File size limit: about 250 MB
Files up to about 250 MB work reliably and take under a minute. Larger files may fail with a "504 Gateway Time-out" error page.
If your file is bigger than that, split it into smaller files and run each one separately. Most spreadsheets are far smaller than this, often under 5 MB.
Tip: Only list name or address columns. Running this on columns like email addresses, IDs or state abbreviations will change their capitalization too.
