About This Tool

The tool analyzes input text and applies formatting transformations to improve readability and consistency across content types. It supports JSON, XML, YAML, Markdown, and plain text, and can be configured to match team conventions for indentation, wrapping, and line endings. Conceptually, it detects structured formats to apply formatters where appropriate while gracefully handling prose. This yields outputs suitable for reviews, publication, or ingestion workflows. Beneficiaries include developers, technical writers, data engineers, and content teams who need uniform styling and reduced manual edits. The tool’s value lies in deterministic formatting, audit-friendly diffs, and adaptable options that cover typical formatting tasks without altering semantic content. Core features include whitespace normalization, indentation standardization, and line wrapping with a configurable width; optional language-aware formatting expands to JSON, XML/HTML, YAML, and Markdown rules. Use cases range from reformatting API payloads for diffs, cleaning configuration blocks, to preparing documentation blocks for release notes. The approach focuses on correctness, repeatability, and speed, enabling consistent outputs across large text blocks. Users benefit from reduced manual edits, faster reviews, and improved readability for downstream processing and collaboration.
The tool avoids altering semantic meaning, preserves code blocks when present, and offers a safe fallback for unparsable content by applying conservative whitespace normalization. It is designed for local or server-side usage in development pipelines and publishing workflows, ensuring the final text adheres to agreed-upon style conventions.
Overall, it provides a pragmatic, language-agnostic formatter that complements code editors and CI workflows, delivering stable, review-friendly formatting results.

Frequently Asked Questions

Find Quick Answers

What formats are supported?
Supported formats include JSON, XML, YAML, Markdown, and plain text. The tool can auto-detect the structure when possible, and applies format rules appropriate to the detected format while preserving non-structured content.
Can I preserve existing line endings?
Yes. You can enable preserve_line_endings to keep LF or CRLF endings as in the original content. If disabled, the formatter uses the configured wrap and indentation style with consistent endings.
What happens with invalid JSON or XML?
For invalid structured content, the tool performs a best-effort whitespace normalization and wrapping pass. Structured parsing errors do not fail the operation; output is reformatted as readable as possible without changing semantic intent.
Is minification supported?
Minification is optional. When enabled, the formatter removes unnecessary whitespace and line breaks to reduce size, which is useful for transmission or storage, while the default behavior focuses on readability.
