I. Creative Inspiration

In our daily work, we often encounter the problem of messy text formatting—for example, text copied from PDFs, web pages, or various editors may contain extra spaces, carriage returns, tabs, or blank lines. These "invisible" characters not only affect the reading experience but can also interfere with data analysis, programming, and content layout.

The original intention of developing this online text cleaning tool is to allow users to quickly clean up redundant characters directly in the browser without the need for complex text editing software, achieving uniform formatting and improving work efficiency.

IV. Implementation Principle

This tool implements text cleaning logic based on Java's native String functions, featuring high performance, low latency, and zero dependencies:

• Remove spaces: replaceAll("\\s+", "") 

• Remove carriage returns and line feeds: replaceAll("[\\r\\n]", "")

• Remove tabs: replaceAll("\\t", "")

• Remove blank lines: Regular expression matches blank lines and deletes them.

• Remove leading and trailing spaces: trim()

By combining options, you can flexibly implement different cleaning rules, ensuring flexibility and accuracy.
