A QVD reader that runs in your browser
A QVD file is the binary table format QlikView and Qlik Sense write when they store data to disk. It is compact and fast for Qlik to reload, but nothing else opens it: not Excel, not a text editor, not pandas. That makes a QVD awkward the moment you need the data somewhere other than Qlik.
This tool reads the format directly. It decodes the XML header, the symbol table and the bit-packed index table, then shows you the fields, the record count and a preview. From there you can convert the QVD to CSV or convert it to Parquet in one click.
Because the parsing happens in your browser, nothing is uploaded and nothing queues behind other people's files. Large exports keep working while the page stays responsive.
How to convert a QVD file
- 1
Open your QVD file
Drop a .qvd file onto the converter or pick it from your computer. The file is read by your browser, not uploaded to a server, so there is no size limit imposed by an upload.
- 2
Check the schema and the preview
The dashboard lists every field with its number of distinct values, the record count and a preview of the first rows, so you can confirm you have the right table before exporting.
- 3
Export to CSV or Parquet
Click Export CSV or Export Parquet. The file is generated in your browser and saved straight to your downloads folder, keeping the original field names.
Frequently asked questions
How do I convert a QVD file to CSV or Parquet?
Open the QVD file in this converter and click Export CSV or Export Parquet. No Qlik installation, no macro and no account is needed: the conversion runs in your browser.
Do I need QlikView or Qlik Sense to open a QVD file?
No. A QVD file is a documented binary format with an XML header, and this tool reads it directly. You can inspect and convert a QVD file on a machine that has never had Qlik installed.
Is my QVD file uploaded anywhere?
No. The file is parsed by a Web Worker inside your browser and never leaves your device. The only thing sent to the server is the number of records, which feeds a public running total.
How large a QVD file can it handle?
Files of several hundred megabytes and tens of millions of rows work: a 404 MB file with about 10 million rows opens in a few seconds. The practical limit is your browser's memory, not an upload timeout.
Is the QVD converter free?
Yes. It is free, needs no sign-up, and there is no row limit or watermark on the exported file.
Should I export to CSV or to Parquet?
Choose CSV to open the data in Excel, load it into any database or share it as plain text. Choose Parquet for analytics: it keeps column types, and the file is typically several times smaller than the same data as CSV.
