I'll create a program that converts strings to ASCII, binary, and 8-bit representations with a clean interface.

This program provides a clean interface for converting strings to ASCII, binary, and 8-bit representations:

1. Enter any text in the input field and click "Convert"

2. The application will display a table showing:

   • Each character
   • Its ASCII code
   • Its binary representation
   • Its 8-bit binary representation (padded with leading zeros if needed)
3. You can copy individual values to your clipboard with the copy buttons
4. The clear button resets the form when you want to start over

The conversion works by:

• Using charCodeAt(0) to get the ASCII code for each character
• Converting the ASCII code to binary with toString(2)
• Padding the binary representation with leading zeros to ensure it's 8 bits long

The interface is fully responsive and provides toast notifications when you copy values to your clipboard.

I'll add options for users to choose between different conversion types.

I've updated the converter to allow users to choose between different conversion types. Now users can select from six different conversion options:

1. ASCII to Binary - Convert text characters to their binary representation
2. Binary to ASCII - Convert binary values to ASCII characters
3. ASCII to 8-Bit - Convert text characters to 8-bit binary representation
4. 8-Bit to ASCII - Convert 8-bit binary values to ASCII characters
5. Binary to 8-Bit - Pad binary values to 8-bit representation
6. 8-Bit to Binary - Convert 8-bit binary to regular binary (remove leading zeros)

Key improvements:

• Added a tab interface to select the conversion type
• Dynamic input placeholders that change based on the selected conversion
• Customized table headers and rows for each conversion type
• Error handling for invalid inputs
• Responsive design with tabs that adapt to different screen sizes
• Clear button to reset the form
• Copy functionality for the converted values

The interface updates dynamically based on the selected conversion type, showing relevant column headers and data. The input placeholder also changes to guide users on the expected format for each conversion type.
