About Text Indenter & Outdenter

This tool helps developers and content editors manage indentation quickly. It is useful for formatting code snippets, JSON/YAML files, markdown documents, and other structured text. Use it to convert indentation styles, clean trailing whitespace, or perform selective indentation of only highlighted lines. The tool runs entirely in the browser and keeps your data private.

How to Use

1. Paste or upload the text into the input area (or drop a file).
2. Choose indentation settings (tab, or 2/4/8 spaces).
3. Use Indent or Outdent to change indentation for selected lines or the whole text.
4. Use Normalize to convert all indentation to your chosen style.
5. Enable Auto-update preview to see changes live, then Copy or Download the processed text.

Pro Tips

• Use Auto-detect to quickly find the indentation used in a file and set the tool to match it.
• Use Selection only to operate on a block of lines inside large files without touching the rest.
• Keyboard shortcuts speed up workflow: Ctrl/Cmd + ] to indent and Ctrl/Cmd + [ to outdent.
• Trim trailing spaces before committing code to version control to keep diffs clean.

FAQs

Why Use Text Indenter and Outdenter Tool?

This precision formatting instrument enables structured text organization through controlled indentation adjustments. Developers use it for code block formatting, technical writers for documentation hierarchy, data analysts for JSON/YAML refinement, and content creators for visual structure enhancement while maintaining syntactic integrity across various programming languages and markup formats.

Does this tool change my original files?

No. All processing occurs locally within your browser environment without file alteration. Use the download functionality to preserve processed text while maintaining original file integrity and version control.

Can I process only a selection?

Yes. The selective application feature enables targeted text processing when "Apply to selection only" is enabled, allowing precise indentation control within specific code blocks or content segments without affecting surrounding text.

Will this break code alignment?

No. The algorithm preserves code integrity by removing only exact matching leading indentation patterns and maintaining blank line structure when requested, ensuring syntactic correctness across programming languages and data formats.

Which languages benefit most?

Python, JSON, YAML, Markdown, HTML, JavaScript and other indentation-sensitive languages gain significant formatting benefits from precise indentation control, structure visualization, and hierarchical organization capabilities.

How does the tool handle nested structures?

The intelligent indentation system recognizes code block boundaries, maintains relative indentation levels, and preserves nested structure integrity during formatting operations for complex programming constructs.

What are the technical applications?

This tool enables code documentation, configuration file formatting, data serialization, technical writing, and presentation preparation where visual hierarchy and structural clarity enhance readability and maintenance.
