Using JSON for Database Seeding from CSV
Whether you're migrating data to MongoDB, seeding a Firebase Realtime Database, or generating SQL INSERT statements via scripts, converting your CSV source file to a properly-typed JSON structure is the essential first step. Our converter creates clean JSON arrays where numeric IDs remain as integers (not strings), booleans are preserved, and empty columns produce null instead of empty strings. The output is immediately usable in MongoDB's mongoimport --jsonArray, Firebase set calls, or any ORM's bulk insert method.
