Welcome to Scriptella ETL Project

About Scriptella

Scriptella is an open source ETL (Extract-Transform-Load) and script execution tool written in Java.

Our primary focus is simplicity. You don't have to study yet another complex XML-based language - use SQL (or other scripting language suitable for the data source) to perform required transformations.

Typical use

  • Executing scripts written in SQL, JavaScript, JEXL, Velocity and many more.
  • Database migration. Interoperability with LDAP, JDBC, XML and other datasources.
  • Cross-database ETL operations, import/export from/to CSV, text and XML and other formats.
  • Alternative for Ant <sql> task.
  • Automated database schema upgrade.


  • Simple XML syntax for scripts. Add dynamics to your existing SQL scripts by creating a thin wrapper XML file:
    <!DOCTYPE etl SYSTEM "">
        <connection driver="$driver" url="$url" user="$user" password="$password"/>
            <include href="PATH_TO_YOUR_SCRIPT.sql"/>
            -- And/or directly insert SQL statements here
  • Work with multiple datasources in a single ETL file. See example of copying a table to another database.
  • Support for many useful JDBC features like batching, prepared statements and parameters in SQL including references to files(BLOBs) and JDBC escaping.
  • Performance. Performance and low memory usage are one of our primary goals.
  • Support for evaluated expressions and properties (based on JEXL syntax). Example of using a JEXL expression to concatenate NAME and SURNAME columns from another datasource:
  • Support for cross-database ETL scripts by using <dialect> elements
  • Transactional execution. Changes are rolled back if a failure occurs while running the ETL.
  • Flexible error handling by using <onerror> elements
  • Conditional scripts/queries execution (similar to Ant if/unless attributes but more powerful)
  • Easy-to-Use as a standalone tool or Ant task. No deployment/installation required.
    Easy-To-Run ETL files directly from Java code.
  • Built-in adapters for popular databases for a tight integration. Support for any database with JDBC/ODBC compliant driver.
  • Service Provider Interface (SPI) for interoperability with non-JDBC DataSources and scripting languages. Out of the box support for JSR 223 (Scripting for the Java™ Platform) compatible languages.
  • Built-In CSV, Excel, Text, XML, LDAP, Lucene, Velocity, JEXL and Janino providers. Integration with Java EE, Spring Framework, JMX , JNDI and JavaMail for enterprise ready scripts.
