Applying a single find-and-replace is straightforward, but converting American spelling to British throughout a document, or renaming several placeholder terms in a template, means running many separate replacements one after another — tedious past a handful of pairs.
This tool lets you define a whole list of find/replace pairs at once, using a simple "find = replace" format on each line, and applies every pair to your text in a single pass.
This is useful for batch spelling conversions (American to British English), renaming multiple placeholder variables in a template, or any text cleanup task involving several systematic substitutions at once.

A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this conversion or calculation often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.

Frequently asked questions
What order are replacements applied in?
Pairs are applied in the order listed, top to bottom — if one replacement could affect a later one, consider the order carefully or test with a shorter sample first.
Is matching case-sensitive?
Yes, matching is case-sensitive by default, so you may need separate pairs for capitalized and lowercase versions of the same word if both appear in your text.
