Clipboard Investigator

Use this tool to see what's really in your clipboard! Just paste using Ctrl+V (or Cmd+V on Mac) to see.

NOTE: none of this data is sent to a server. The JS code is simple enough that you can see everything that happens via Inspect Element.

More Details
  1. Copy something from any source you'd like (a web page, Notion, the terminal, etc.)
  2. "Paste" on the page (hit Ctrl+V or Cmd+V)
  3. See the full extent of what's in your clipboard: not just the text, but also the different types of text

I built a version of this for a bug I ran into at work. It helps me debug exactly what is being copied and pasted into my app. Helpful when debugging paste issues with a rich text editor.

For example, if I copy my footer:

It will produce the following output:
