About this Gig
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.
csv to sql
excel to database
data import
postgresql
mysql
