How to save response data in to CSV in Jmeter - csv

I am trying to save Jmeter response in CSV file. I have tried some of the answers from StackOver Flow but those are not working.
Can anyone suggest me how can I achieve this?
Note: I have tried this and this.

Most probably it is something not feasible when it comes to CSV files as response data can have delimiter characters which will break your CSV file structure. For example if you use comma as delimiter and your response data contains commas - it will be not possible to save the response into a single CSV "cell".
If you need to save the response data I would recommend using XML format of the .jtl results file for this. You can amend JMeter's default result file configuration as follows:
Add next lines to user.properties file:
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
That's it, next time you run JMeter in command-line non-GUI mode as:
jmeter -n -t test.jmx -l result.xml
the result.xml file will contain the response data which can be examined using either View Results Tree listener or XML viewer/editor of your choice.

If the response of your request can be stored in csv then you can use one of the following
'Save Responses to a file' in Listeners.
Capture the response using regular expression extractor and write the value to a file in Beanshell code.

JMeter GET Request – How do you add query parameters from .csv file?

I am having issues with successfully making a GET http request with query parameters reading from a .csv file. I am working with a JSON application. Thank you bunches in advance!
Path: /mortgagecalc/?amount=${amount}&years=${years}&maxInterest=${maxInterest}
CSV Data Set Config
HTTP GET Request
I don't see any "issues" with your configuration
Given you have test.csv file which looks like this:
1,2,3
4,5,6
7,8,9
your setup should read the next line on next iteration and populate request details with the values from the CSV file:
If this is not the case for you:
Check the path to the CSV file, it must exist and be readable otherwise your request won't be executed
Check jmeter.log file for any suspicious entries
Check generated JMeter Variables using Debug Sampler and View Results Tree listener combination

How to save response data to CSV file that i am generating in Simple Data Writer in JMeter

I am executing one Thread Group which have multiple Http Request. And I am capturing the Error result into a CSV file using Simple Data Writer. But unable to add the response data to the same file. Can you guys please let me know how I can add the response data to this CSV file or is there any other way that we can use for this purpose?
Use simple data writer but change the option to produce XML. Remove CSV and select "Save as XML". There is a option to "Save Response Data(XML)" that is what you require as shown below.
Put the result file output format as ".jtl" and open it in the Excel to see the results.
You don't even need to Simple Data Writer for this, it can be done by amending JMeter Results File Configuration:
Add the next lines to user.properties file (lives in "bin" folder of your JMeter installation)
jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data.on_error=true
Restart JMeter to pick the properties up
Next time when you run JMeter in command-line non-GUI mode like
jmeter -n -t test.jmx -l result.jtl
response data for failed samplers will be added to the results.jtl file, you will be able to inspect it using either View Results Tree listener or your favorite text/XML viewer/editor.

Loading JSON data with CSV Data Set Config

I'm new to Jmeter so I hope this question is not too off the wall. I am trying to test an HTTP endpoint that accepts a large JSON payload and processes it. I have collected a few hundred JSON blobs in a file and want to use those as my input for testing. The only way that I have come across for loading the data is using the CSV config. I have a single line of the file for each request. I have attempted to use \n as a delimiter and have also tried adding a tab character \t to the end of each line. My requests all show in put of<EOF>.
Is there a way to read a file of JSON objects, line at a time, and pass them to my endpoint as the body in a POST?
You need to provide more information, to wit: example JSON file (first 2 lines), your CSV Data Set Configuration, jmeter.log file, etc. so we could help.
For the time being I can state that:
Given CSV file looking like:
{"foo":"bar"}
{"baz":"qux"}
And pretty much default CSV Data Set Config setup
JMeter normally reads the CSV data
Be aware that there are alternatives to the CSV Data Set Config, for example:
__CSVRead() function. The equivalent syntax would be ${__CSVRead(test.csv,0)}
__StringFromFile() function. The equivalent syntax would be ${__StringFromFile(test.csv,,,)}
See Apache JMeter Functions - An Introduction to get familiarized with the JMeter Functions concept.

JMeter read the second sheet of CSV

How can I make JMeter read the second sheet of my CSV?
I want to use CSV Data Set Config.
Normally, it reads the first line of the first sheet but is there any way to be a bit more flexible?
CSV file format doesn't have "sheets", it is a normal plain text file using delimiters in order to represent structured data.
If you are trying to get data from i.e. Microsoft Excel file type - unfortunately you won't be able to do it using CSV Data Set Config. The easiest would be exporting data as separate plain-text CSV files.
If you don't have the possibility to do the export you still can access the data from Excel files but it will be a little bit more tricky as you will have to use JSR223 Test Elements, Groovy language and Apache POI libraries
More information:
Busy Developers' Guide to HSSF and XSSF Features
How to Extract Data From Files With JMeter
Currently you can use CSV Data Set Config for that, you should add external code for example using Apache Commons CSV,
Download the jar file and place it in JMETER_HOME lib folder, and then write the code in JSR223 Element.
Examples exists, code for get second record:
Reader in = new FileReader("path/to/file.csv");
Iterable<CSVRecord> records = CSVFormat.RFC4180.parse(in);
// go to next record
records.next();
CSVRecord secondRecord = records.next();
//columnOne = secondRecord.get(0);

How to export JMeter results to JSON?

We run load tests with JMeter and would like to export result data (throughput, latency, requests per second etc.) to JSON, either a file or STDOUT. How can we do that?
JMeter can save the results in a CSV format with header.
(Do not forget to select Save Field Names - it is OFF by default)
Then you can use this tool to covert the CSV to a JSON.

EDIT
JMeter stores the result in XML or CSV format. XML is by default (with .jtl extension). But It is always recommended to save the result in csv format.
If you want to convert XML to JSON
http://www.utilities-online.info/xmltojson/#.U9O2ifldVBk
If you are planning to use CSV, To save the result in CSV format automatically
When you are running your test via command line, to save the result in csv for a specific test
%JMETER_HOME%\bin\jmeter.bat" -n -t %TESTNAME% -p %PROPERTY_FILE_PATH% -l %RESULT_FILE_PATH% -j %LOG_FILE_PATH% -Djmeter.save.saveservice.output_format=csv
Or
You can update the jmeter.properties in bin folder to enable below property (for any test you run)
jmeter.save.saveservice.output_format=csv
Hope, it is clear!
There is no OOTB solution for this but you could inspire yourself from this patch:
