Over deze dienst

I convert and migrate data between any common format and any SQL database, in either direction.

Formats: CSV, Excel (XLSX), JSON, XML, Parquet, SQLite, PostgreSQL, MySQL.

What I do:

File or database to SQL (PostgreSQL, MySQL, SQLite)

SQL database to CSV, Excel, JSON, XML, or Parquet

Data cleaning and duplicate removal

Proper table design with real relationships, not one flat dump

Reusable conversion/import scripts

Data validation before and after conversion

I have handled everything from small business spreadsheets to large datasets, recently 2+ billion rows for a financial platform, so format and size are not usually a problem.

Send me a sample file (or database export) and your target format, and I will confirm the approach before you order.
