Databases tips

🗄️

Most databases have LOAD DATA or COPY commands that accept CSV files. Convert your JSON here, download the CSV, and use it for bulk import.

💡

MySQL: LOAD DATA INFILE 'file.csv' INTO TABLE t FIELDS TERMINATED BY ',' ENCLOSED BY '"'. The converter outputs RFC 4180-compliant CSV.

🔧

PostgreSQL: \COPY tablename FROM 'file.csv' CSV HEADER. The CSV header row matches column names — verify they match your table schema.

📋

Verify row count: the JSON array length should equal the number of CSV data rows (excluding the header). Check this before importing to a live database.
