Rating Normalization
Extract clean numeric ratings from various formats including fractions, stars, and text.
Review ratings come in many formats — "4.5 out of 5", star characters, fractions, even written-out numbers. Rating normalization extracts a clean numeric value that works in databases, APIs, and schema markup.
Rating (Extract Number)
Extracts a clean numeric rating from virtually any format. Handles fractions (4.5/5), "X out of Y" text, written numbers (four point five), star characters (★★★★½), and plain numbers.
