This tutorial shows how to extract data from QVD files in Advanced ETL Processor. Use the QVD Reader when you need to read QlikView or Qlik Sense data files in an automated workflow, without running Qlik on the processing machine.
What You Will Learn
- Configure the QVD Reader as the transformation source.
- Read the single table stored inside a QVD file.
- Check QVD metadata before mapping fields downstream.
- Avoid numeric field problems caused by date or timestamp detection.
Before You Start
Use a test repository or safe sample data while following the tutorial. Production jobs are a poor place to experiment.
QVD Reader Docs
This tutorial uses the QVD Reader to read a Qlik data file as a transformation source. A QVD file stores exactly one table, so the first job is simple: read that table cleanly before mapping it anywhere else. Simple is good. Simple usually means fewer support tickets.
The QVD Reader documentation explains what QVD files contain: a UTF-8 XML header, symbol tables, and the actual table data. Review this when field names, metadata, or table structure do not look the way you expected.
Check the reader properties before scheduling the transformation. If numeric values are being treated as dates or timestamps, use the Ignore format option to force those values to stay numeric.
