This application parses CSV files (including huge ones) within the browser. It analyzes each field to suggest the best database field type, max length, and whether or not there are any null values. From there, you can rename fields, ignore them, override field types/lengths, etc. and generate database table creation sql for MySQL, MariaDB, Postres, Oracle, or SQLite3. This application uses PapaParse for CSV parsing and Knex.js for SQL query building.
