How do I create a macro to convert a value to a JSON key-value pair?

Explanation

This macro transforms a plain word into a JSON key-value pair format, useful for converting lists of field names into JSON structure.

How it works

1. qa — start recording
2. I" — insert opening quote at line start
3. <Esc> — back to normal mode
4. A": "", — append key-value syntax at end
5. <Esc>j — back to normal, move down
6. q — stop recording

Example

name
age
email

After running on each line:

"name": "",
"age": "",
"email": "",

Tips

• Modify for different formats (YAML, TOML, etc.)
• Use {count}@a to process multiple lines
• Customize the value placeholder as needed
• Combine with :g/./normal @a for non-blank lines only
