Examples

1. CSV to PostgreSQL multi-row INSERT

Data analyst

Background

An analyst has a small comma-separated orders table with integer IDs, customer names, and decimal amounts.

Problem

The table must be converted into one PostgreSQL multi-row INSERT with the amount column's blank value treated as empty input.

How to use

Paste the CSV, select PostgreSQL and comma as the delimiter, set the table name to orders, keep the first-row header option enabled, and enable multi-row VALUES.

{"dialect":"postgresql","delimiter":"comma","tableName":"orders","nullStyle":"empty","conflictMode":"none","batchSize":100,"multiRow":true,"hasHeader":true,"includeSchema":false}

Outcome

The tool infers BIGINT, TEXT, and DOUBLE columns and produces a PostgreSQL multi-row INSERT batch.

2. Semicolon CSV to MySQL upsert
