What can this tool do?

Change case, reverse text, clean blank or duplicate lines, sort and shuffle lines, extract numbers or letters, convert punctuation, format JSON, replace text and add prefixes or suffixes. All processing happens in your browser.

What this tool does

Clean and reshape text without moving it to a server. The editor shows line and character counts so you can see the effect of each operation.

How to use it

  1. Paste or type text into the input panel.
  2. Choose an operation such as case conversion, line cleanup, sorting or JSON formatting. Use the dedicated forms for find and replace or line prefixes and suffixes.
  3. Review the result, apply another operation if needed, then copy it.

Understand the controls

Chaining operations
Each new operation uses the current result. Edit the original input to start a new sequence.
Structured input
Format JSON parses the text before indenting it. Invalid JSON produces an explicit error rather than a changed result.

Example

To clean a pasted list, remove blank lines, remove duplicates and then sort. Check the line count after each step.

Files and limits

Processing happens in this browser tab. Save the final text before closing the page if you need it later.

Frequently asked questions

Is my text uploaded?

No. Every text operation runs in your browser. Your input is not sent to a server.

Can I apply several operations in sequence?

Yes. Each operation uses the current result. Edit the original input to start again.

What does Format JSON do?

It parses valid JSON and prints it with indentation. Invalid JSON produces an explicit error.
