SQL Database Generation Code Refactoring

I have Perl code that converts an sqlite database from one format/structure to another. It is somewhat convoluted and I would like to have the code refactored to NodeJS so that it is easier to maintain. Some of the conversions depend on variables and I would like these to be declared at the beginning of the code so that they can be adjusted easily if necessary. I have the two sqlite files and the Perl code for reference so it should be a straightforward job. Thank you for considering my project!
