ASCII Validator

The ASCII Validator analyzes input text to determine ASCII compliance. It targets developers, data engineers, and teams handling legacy systems, logs, and data transfers that require ASCII-only content. Conceptually, the tool scans code points and marks any character outside the 7-bit ASCII range (0–127). It can operate in ASCII-only mode or an extended mode that permits 128–255. The core result is a compliance flag, a per-character report, and an optional sanitized version that can be used downstream.

Key features include: per-character non-ASCII reporting with indices and code points; a count of offending characters; a sanitized_text produced by removing or replacing non-ASCII depending on configuration; and an optional batch mode for multiple inputs. Use cases: ensuring data sent to legacy APIs, preparing CSV or log lines, and auditing multilingual content for ASCII pipelines.

Differentiation: this tool emphasizes deterministic reporting and local processing with zero external dependencies; outputs are ready for automation, audits, or integration into CI pipelines. It supports both strict ASCII checks and extended ASCII allowances, and it can map or strip non-ASCII characters to deliver predictable results. It is particularly valuable for teams migrating to ASCII-based protocols, data lakes with ASCII constraints, and engineering workflows requiring reproducible results.
