How Client-Side Data Conversion Works
Data conversion takes raw text in a source syntax and transforms it into a target schema or format. The input is first parsed into an abstract syntax tree (AST) or typed in-memory objects. The converter normalizes data types, resolves nested structures, escapes special characters according to target specifications, and serializes the result into the destination format—all executed in real time inside your browser memory without server uploads.
