SAS Code Formatter

The SAS code formatter online is a language-aware tool designed to improve readability and maintainability of SAS scripts. It recognizes common SAS constructs such as DATA steps, PROC steps, SET statements, IF/THEN/ELSE logic, DO blocks, and macro references, and applies consistent indentation and line breaks without altering execution semantics. Users can paste code or load text from files, and receive a formatted version that aligns with internal or industry-standard styles. This reduces cognitive load during reviews and accelerates collaboration.
Conceptually, the formatter runs through the source in two passes. The first pass tokenizes SAS syntax and identifies statement boundaries, comments, and macro sections. The second pass applies indentation rules based on block depth, uppercases or preserves keywords per settings, and wraps long lines to a configurable maximum length. Comments remain attached to their lines, and labels or trailing semicolons are preserved. No runtime evaluation occurs; output is strictly a presentation-friendly reformatting.
Who benefits includes SAS developers, data teams in consulting and industry, instructors building teaching materials, and students preparing class examples. Typical use cases are preparing code for peer reviews, creating documentation snippets, sharing examples in reports, and enforcing consistent style guidelines across projects. Teams can define presets for indentation and casing to ensure uniformity in pull requests and repositories.
Unique value comes from domain-specific rules tailored to SAS syntax, support for both DATA and PROC contexts, and optional presets that match organizational standards. The tool is non-executable, making it safe to integrate into CI pipelines or local workflows. It supports standard line endings, preserves comments, and provides a lightweight, fast formatting experience suitable for frequent iterations.
