I was not able to open SAZ file directly into Jmeter, followed below steps:
First we have to convert SAZ file to HAR file
To convert a SAZ file to a .Jmx file:
- Double-click on the saved SAZ file, it should open Fiddler. Install Fiddler from Fiddler Download Page if necessary,
- Click on File > Export > All Sessions > HTTP Archive 1.2.
- Save HAR file
- Go to https://converter.blazemeter.com/ , upload your HAR file on the site , it will convert it into JMX.
- Open same JMX in your Jmeter.
