Intelligent Data Mapping

Our conversion engine analyses your files and intelligently handles text, numeric, decimal and date data types to ensure your database tables are set up to be efficient and lighting fast.

Enterprise Grade Security

SQLizer is HTTPS-only, with all converted files kept in secure storage, encrypted at rest and automatically deleted within 48 hours (7 days for signed-in users).

During this period users can choose to manually delete files as soon as a conversion completes if they prefer. For more information see our Privacy Policy.

Powerful API

Our REST API enables you to push data into relational databases as part of your big data analytics or BI pipeline.

With our paid plans, there's no limit on the number of files you can convert, the size of those files, or the number of concurrent conversions you can run.
