About

Copy Hero converts lists of text that are separated by newlines and converts them into a JSON array or a list of SQL-style VALUES and copies it to your clipboard. You can then paste this list into a script or a SQL statement.

As an example use-case, you may be given a long list of ids in a spreadsheet to lookup in the database. With Copy Hero, simply copy the rows and paste them into the extension to have them converted into a useful format.

Copy Hero can be used in two ways. You can either manually paste the list into its text input, or you can use a keyboard shortcut to automatically have it read from your clipboard and write the structured list back to it. The first time you use the keyboard shortcut, you will need to allow Copy Hero to access your clipboard.
