how to get all data from csv into jmeter? - csv

Question

I have a table on the page with maximum of 20 rows and also I created a CSV file with 20 rows in it.
Current Scenario : Jmeter is picking only one row for one user from csv file.
Required: I need jmeter to read all rows (i.e 20) for one user.
Table:
Name1 ---- roll1 --- PhnNumber1 --- date1 --- month1 --- year1 --- Dept1
Name2 ---- roll2 --- PhnNumber2 --- date2 --- month2 --- year2 --- Dept2
Name3 ---- roll3 --- PhnNumber3 --- date3 --- month3 --- year3 --- Dept3
.
.
.
Name20 ---- roll20 --- PhnNumber20 --- date20 --- month20 --- year20 --- Dept20
CSV file:
Name --- roll --- PhnNumber --- date --- month --- year --- Dept

20.
So I do I configure Jmeter to read all 20 data from csv file for one user.

Answer 1

It's not clear in which format you want to ingest the contents of the CSV file.
Given your CSV file looks like:
Name1,roll1,PhnNumber1,date1,month1,year1,Dept1
Name2,roll2,PhnNumber2,date2,month2,year2,Dept2
Name3,roll3,PhnNumber3,date3,month3,year3,Dept3
If you need it fully inline or in a JMeter Variable (hopefully this is what you're looking for) - there is __FileToString() function
If you want individual values you can go for __CSVRead() function
${__CSVRead(test.csv,0)} - will give you Name1
${__CSVRead(test.csv,1)} - will give you roll1
${__CSVRead(test.csv,next)} - will proceed to the next row
If you want something custom - there is __groovy() function where you have the full freedom regarding how to read the file and where and how to store the results
