We want to use 100 credentials from .csv but I would rather like to know if there is any other alternative to this available in jmeter.
If you have the credentials in the CSV file there are no better ways of "feeding" them to JMeter than CSV Data Set Config.
Just in case if you're still looking for alternatives:
__CSVRead() function. The disadvantage is that the function reads the whole file into memory which might be a problem for large CSV files. The advantage is that you can choose/change the name of the CSV file dynamically (in the runtime) while with the CSV Data Set Config it has to be immutable and cannot be changed once it's initialized.
JDBC Test Elements - allows fetching data (i.e. credentials) from the database rather than from file
Redis Data Set - allows fetching data from Redis data storage
HTTP Simple Table Server - exposes simple HTTP API for fetching data from CSV (useful for distributed architecture when you want to ensure that different JMeter slaves will use the different data), this way you don't have to copy .csv file to slave machines and split it
There are few alternatives
JMeter Plugin for reading random CVS data : Random CSV Data Set Config
JMeter function : __CSVRead
Reading CSV file data from a JSR223 Pre Processor
CSV Data Set Config is simple, easier to user and available out of the box.

I have encounter a challenge where I have to read a CSV file and read it till a defined variable size limit( BATCH_SIZE). Once the no of lines from CSV has been read then send it to different AWS API. As my CSV file size can be anywhere 1Gb to 2Gb, therefore I am avoiding to use JSR223 CSV file read.
I want to know how can I can achieve it with JMeter and CSV Data Set Config.
Theoretically you can achieve it using CSV Data Set Config by putting it under the Loop Controller and using your BATCH_SIZE as the loop count.
Another option is importing your CSV file to the RDBMS and use JMeter's JDBC Request sampler for accessing the data
Another solution could be by placing the CSV Data Set Config under a While Controller.
${__groovy(vars.get("__jm__WC__idx").toInteger()< vars.get("BATCH_SIZE").toInteger())}
Test scenario: The folder contains multiple CSVs. Columns are same in all the CSVs.I have to pass multiple csv files one after the other to the single REST API (GET CALL).
Each user (Total 1000 users) should get assigned a set of records/rows from csv file currently in use.
I am new to the JMeter and finding a solution using the CSV Data Set Config. And I realize I could not pass multiple csv files using this.
I also see that __CSVRead() function but I could not pass dynamically the csv file using BeanShell scripting.
Can someone please help me with this?
The CSV file names from the folder can be read one by one using Directory Listing Config plugin
Depending on the CSV file nature you might want to use either __CSVRead() or __StringFromFile() functions directly in your HTTP Request sampler, you don't need to go for any scripting.
Data from CSV file is not reading in jmeter slave system

Actually CSV files are not copied automatically in Slave systems, you need to place the CSV required to Slave systems manually as per the path mentioned in CSV Data Set Config element. Use Absolute path.

I have a directory with CSV files. each file contains a list of GET requests I'd like to make with JMeter. What I'd like to do is read all the files in a directory, and then loop through each CSV to send the requests in JMeter. The number of files isn't consistent so I don't want to hard code the file names into CSV samplers.
So in effect I'd like to read all the files in the directory and store the files in an array variable. The loop through the array and send the CSV file to the CSV sampler which will in turn read the CSV file and pass the content to an HTTP Request sampler to send the GET requests.
I created a beanshell script to read the files in the directory and store them in an array, but when I try to pass this to the CSV config element, I get errors stating the variable doesn't exist.
I've tried another beanshell script to read the file and pass the lines to an HTTP request Sampler as a variable, but the issue was, it would store all the file contents in memory per thread.
I'd like to know the best approach to read the files, send the requests and use the response data to generate reports
You will not be able to populate CSV Data Set config using Beanshell as CSV Data Set Config is a Configuration Element and according to Execution Order user manual chapter Configuration Elements are executed before anything else.
Since JMeter 3.1 you should not be using Beanshell, it is recommended to switch to JSR223 Elements and Groovy language
I would recommend going for Directory Listing Config plugin, it scans the provided folder (in your case with CSV files) and stores the found paths to files into a JMeter variable
So you can use the Directory Listing Config in combination with __StringFromFile() or __CSVRead() functions and that should be more or less good way of implementing your requirements.
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,,,)}
