Core Features

HTML Input & Analysis

The first step is to paste your HTML code into the text area. BlastBox Code supports:

  • Complete HTML documents
  • HTML fragments and snippets
  • Complex nested structures
  • HTML with inline styles and scripts
<!DOCTYPE html> <html> <head> <title>My Website</title> </head> <body> <h1>Welcome to My Site</h1> <p>This is some content to edit.</p> </body> </html>

Text Node Editing

After analysis, BlastBox Code presents all editable text in an organized list:

  • Each text node shows its location in the HTML structure
  • Original text is preserved for reference
  • Edit fields allow easy content modification
  • Changes are tracked and highlighted
Smart Detection: Only meaningful text content is extracted - scripts, styles, and empty nodes are ignored.

Change Preview

The preview feature shows you exactly what will change:

  • Side-by-side comparison of original vs. modified text
  • Color-coded changes (red for removed, green for added)
  • Context information showing where changes occur
  • Real-time updates as you make edits

Export Options

Once you're satisfied with your changes:

  • Download HTML: Save the modified HTML as a file
  • Copy to Clipboard: Copy the HTML code for pasting elsewhere
  • Original formatting and structure are preserved
  • Only text content is modified - all HTML tags remain intact
