Convert XML to QVD Automatically
Need to convert structured XML data into QlikView’s QVD format? With Advanced ETL Processor, you can generate QVD files directly from XML sources - without scripting, XSLT, or Qlik macros.
What Is a QVD File?
QVD (QlikView Data) is a high-performance proprietary file format used by QlikView and Qlik Sense to store data tables. It allows for fast, optimized loading during dashboard refreshes and data modeling tasks.
While QVDs are typically created within Qlik apps, Advanced ETL Processor enables you to build QVDs from external data sources such as XML, SQL databases, Excel files, and more - completely outside Qlik.
Why Convert XML to QVD?
- Automate data feed into QlikView from XML APIs or exports
- Optimize load performance with pre-built QVD layers
- Simplify data transformations before loading into Qlik apps
How to Convert XML to QVD - Step-by-Step
1. Launch Advanced ETL Processor
Start the Enterprise Edition. Under Tools > Connections, define:
- XML File connection for the input
- QVD Writer connection for the output
2. Create a New Transformation
Right-click on a transformation group and select New to open a blank dataflow canvas.
3. Configure XML Reader
- Drag the XML Reader onto the canvas if necessary
- Double-click to open Properties
- Select your XML file
- Select Table and Record XML Tags
4. Configure QVD Writer
- Drag the QVD Writer onto the canvas
- Double-click to open Properties
- Select the destination QVD file path
5. Map Fields and Transform Data
Connect and map fields between XML and QVD. You can:
- Convert text, numeric, and date formats
- Apply logic, formulas, or filtering
- Clean and normalize incoming data
6. Generate the QVD
Click Execute to create a QVD file. The result is ready for loading directly into QlikView or Qlik Sense applications.
Automation Options
- Schedule XML-to-QVD conversion with the built-in scheduler
- Trigger based on file arrival, FTP, or HTTP download
- Enable logs, email alerts, and rollback
Where this conversion fits
Convert XML to QVD Automatically is useful when a file has to feed a database, dashboard, partner upload, report, archive, or downstream ETL job. Use it when the same XML input needs controlled QVD output, validation, and logs instead of another manual export.
Do not automate the conversion until the output format, file naming, data types, and failure rules are agreed. Automation repeats rules; it does not rescue unclear ones.

FAQ
Can Advanced ETL Processor handle Convert XML to QVD Automatically?
Yes. Advanced ETL Processor can convert XML to QVD, validate the data, and log the workflow run.
Do I need to write a script?
No scripting is required for routine conversion, validation, scheduling, and logging. Use scripts only when the rule genuinely needs custom code.
Can I convert multiple XML files at once?
Yes. Point the reader at a folder and use a file mask so matching XML files are processed in one package. That is usually safer than opening files one by one and hoping Monday behaves like Friday.
Can the QVD output be created on a schedule?
Yes. The package can run on a schedule or as part of a larger ETL process, then write the QVD output with the same naming and validation rules each time.
What should I check before the first production run?
Check headers, data types, date formats, decimal separators, encodings, empty values, and output file naming. Most conversion problems hide in those details, usually wearing a spreadsheet hat.
Can failed rows or bad files be logged?
Yes. Add validation rules and logging so failed records, rejected files, and run status can be reviewed after execution. A silent conversion failure is just a mystery with a filename.
When should I not automate this conversion yet?
Do not automate it until source columns, data types, output naming, and error handling are clear. Conversion repeats rules; it does not repair vague ones.
Can I try it before buying?
Yes. Download the fully functional 30-day trial and build one small conversion package first.
