CSV Search & Replace: a worked example

A country column mixes "USA", "U.S.A.", and "United States" and you need one canonical value.

Operation

In "country": replace /U\.?S\.?A\.?|United States/ → "US"
CSV Search & Replace produces

Output

3,902 cells normalised across 1 column; other columns safe

Scoped, optionally regex-based replace lets you clean one column without the collateral damage of a global find-replace that would also rewrite unrelated text. The change count confirms the rule did what you expected before you export.

Frequently asked questions

Can I limit the replacement to one column?

Does it support regex capture groups?

Yes. Use $1, $2, etc. in the replacement string to reference captured groups from your regex pattern.
