How to Use This Collection
This page lists ten separate tools. Choose a card to open the tool that matches your task, then enter text, change its available options, and use its result controls. The collection does not chain the tools into one combined pipeline.
- Select a card and open its separate tool page.
- Paste text or use Upload where that tool provides it.
- Adjust the visible options, then review the result produced by that tool.
- Use Copy or Download where available.
Choose a Tool for the Task
Use the cleanup tools to change text, the validation and extraction tools to inspect content, or the analysis tool to measure it.
- Trim Whitespace removes leading and trailing spaces from each line. It also offers Collapse inner spaces.
- Remove Stop Words removes common English stop words and includes Case sensitive.
- Remove HTML Tags keeps readable text from HTML and offers Decode HTML entities.
- Remove Non-Printable Characters removes non-printable characters. Use Keep tabs and Keep newlines to preserve those characters.
- Remove BOM removes a leading byte order mark from text.
- Remove Duplicate Lines compares lines and offers Case sensitive and Trim spaces before comparing.
Use the Cleanup Controls
Controls belong to the selected tool, not to the collection as a whole. For example, Trim leading spaces and Trim trailing spaces control which ends of each line are changed, while Collapse inner spaces changes repeated spaces inside a line.
Unique only is available in Extract URLs and Extract Emails. In Extract Emails, Convert to lowercase normalizes the extracted addresses and Domain filter limits results to the entered domain. In Extract URLs, Strip trailing punctuation removes punctuation at the end of extracted URLs.
Validate, Extract, or Analyze Text
- JSON Validator & Formatter has Validate & Format and Tree View panels. Its options include Indent, Quotes, Sort keys, Minify, and Fix JSON. It follows standard JSON, not JSON5 or YAML.
- Extract URLs returns URLs found in the input and offers Unique only and Strip trailing punctuation.
- Extract Emails returns email addresses and offers Unique only, Convert to lowercase, and Domain filter.
- Text Analyzer reports Words, Characters, Chars (no spaces), Sentences, Paragraphs, Lines, Unique Words, Syllables, reading and speaking time, readability, lexical density, keyword frequency, and longest words. It does not provide a token counter or shown result Copy/Download controls.
Limitations and Processing Scope
The collection page does not define shared file-format, size, or error rules. Check the selected tool page for its own input handling and behavior. The collection itself does not send text to an LLM and does not provide an integrated pipeline.
