Jmeter , How to pass comma seperated multiple values in jmeter - csv

Sometimes for same param I have to send multiple values ,Please find the details of the request below
GET Request with parameters
http://samplelink.com?name=john,mary,souds
http://samplelink.com?name=ram
http://samplelink.com?name=john,mary,souds,lakhan,jaby
How do I use this in jmeter at runtime to pick the values ? and what should be the file content of csv config.

You can still use CSV Data Set Config, either by using double quotes:
Meter allows values to be quoted; this allows the value to contain a delimiter. If "allow quoted data" is enabled, a value may be enclosed in double-quotes. These are removed. To include double-quotes within a quoted field, use two double-quotes. For example:
1,"2,3","4""5"
Or use different delimiter as # to get values from CSV file:
Delimiter Delimiter to be used to split the records in the file. If there are fewer values on the line than there are variables the remaining variables are not updated - so they will retain their previous value
For example file would be:
1#2,3#4,5

The easiest is going for __StringFromFile() function.
For example you have file names.txt in JMeter's "bin" folder with the following content in it:
john,mary,souds
ram
john,mary,souds,lakhan,jaby
Once done you can just use __StringFromFile() function in the HTTP Request sampler "Path" field like:
http://samplelink.com?name=${__StringFromFile(names.txt)}

structure in getMetadata activity for csv file dataset ignores an extra comma in the files first row

I am using a reference CSV file with just the correct number and name of columns and want to compare its structure with that of incoming CSV files before proceeding to use Copy Data to import the incoming CSV data into Azure SQL. Files arriving in blob storage trigger this pipeline.
The need to validate the structure has arisen due to random files arriving with a trailing comma in the header row which causes a failure in the copy data pipeline as it sees the trailing comma as an extra column.
I have set up a getMetadata for both the reference file & the incoming files. Using an If Condition, I compare schemas.
The problem I have is that the output of getMetadata is ignoring the trailing comma.
I have tried 'column count' & 'structure' arguments. The same problem either way as the getMetadata fails to see the trailing comma as an issue.
Any help appreciated
I tried with extra commas in header of csv file. Its not ignoring them
reading those extra commas also as columns.
Please check below screenshots.

JMeter read / write to CSV Data Set Config

So I am loading data from CSV Data Set Config, what I like to do is write a value of a variable back into the next column of that same file in the same row but on the next column.
I check "url" for some specific response json, extract and create a variable "status" and "action" and add it to the row
Is it even possible to write back to the source csv file? Maybe some post processor script? Searching here is like a needle in a haystack sometimes.
It is possible but I wouldn't recommend it as if you implement this post-processor logic and run your test with > 1 user most probably you will get into a race condition when several threads are concurrently writing into the same file.
Alternatives are:
Adding your status and action variables values to JMeter's .jtl result file, just declare the following Sample Variables:
sample_variables=url,status,action
in the user.properties file and next time you run JMeter in command-line non-GUI mode you will see 3 extra columns in the .jtl results file holding the values of these 3 JMeter Variables
If you want a separate file - first of all execute step 1 and then add a Flexible File Writer to your Test Plan and configure it to write the variables into a file, the relevant configuration would be something like:
variable#0|,|variable#1|,|variable#2|\r\n

How to write a JSON extracted value to a csv file in jmeter for a specific variable

I have a csv file that looks like this:
varCust_id,varCust_name,varCity,varStateProv,varCountry,varUserId,varUsername
When I run the HTTP Post Request to create a new customer, I get a JSON response. I am extracting the cust_id and cust_name using the json extractor. How can I enter this new value into the csv for the correct variable? For example, after creating the customer, the csv would look like this:
varCust_id,varCust_name,varCity,varStateProv,varCountry,varUserId,varUsername
1234,My Customer Name
Or once I create a user, the file might look like this:
varCust_id,varCust_name,varCity,varStateProv,varCountry,varUserId,varUsername
1234,My Customer Name,,,,9876,myusername
In my searching through the net, I have found ways and I'm able to append these extracted variables to a new line but in my case, I need to replace the value in the correct location so it is associated to the correct variable I have set up in the csv file.
I believe what you're looking to do can be done via a BeanShell PostProcessor and is answered here.
Thank you for the reply. I ended up using User Defined Variables for some things and BeanShell PreProcessors for other bits vs. using the CSV.
Well, never tried this. But what you can do is create all these variables and set them to Null / 0.
Once done, update these during your execution. At the end, you can concatenate these with any delimiter (say ; or Tab) and just push in CSV as a single string.
Once you got data in CSV, you can easily split in Ms excel.

Getting multiple values from a single cell in .CSV file in jmeter

How can I read multiple values from a single cell in CSV file in jmeter . I have an excel sheet as .csv input and one of its column has mobile numbers which have 2 or more values.eg
987#765#456 Which sampler should I use.
now I want it to split at # as 987,765,456
To read the csv file in JMeter, use CSV data set config.
Check this link to understand how to use CSV data set config in JMeter.
Lets assume the column name is mobileNo which has the value as 987#765#456.
Use Beanshell preprocessor to replace '#' by ','.
mobileNo = vars.get("mobileNo");
mobileNo = mobileNo.replace("#", ",");
vars.put("mobileNo",mobileNo);
You can use JMeter's __javaScript function to replace all occurences of # with , as follows:
Given that your 987#765#456 bit lives as ${mobileNumber} JMeter Variable:
${__javaScript("${mobileNumber}".split('#').join('\,'),mobileNumber)}
The script above replaces all "at" signs with commas and stores the result in "mobileNumber" JMeter Variable.

How to deal with a string with comma in it from a csv, when we have to read the data by using loadrunner?

When I used Loadrunner, it can read data from a csv file. As we know , csv file is separated by a comma.
The question is, if the parameter in csv has comma itself, the string will be separated to several segments. That is not I want to get.
How can we get the original data with comma in it?
When data has a comma, use an escape character to store the data in the parameter.
For example, if the name is 'Smith, John', it can be stored as Smith\, John in the Loadrunner data file.
When you save a file in Excel that has commas in the actual cell data, the whole cell will be inside two " characters. Also it seems that cells with a space in them are inside " chars.
Example
ColA,ColB,"ColC with a , inside",ColD,ColE
More info on CSV file format: http://www.parse-o-matic.com/parse/pskb/CSV-File-Format.htm
The answer to the question is that perhaps the easiest way to do deal with , separators is to change the separator to a ; character. This is also a valid separator in CSV files.
Then the example would be:
ColA;ColB;"ColC with a , inside";ColD;ColE
Maybe the right way is to use C functions to read data from the file (for example fopen/fread)? When you have read it you be able to use "strchr" to find first quotes char and second quotes char. All in that interval would be a value, and it doesn't matter if comma is inside.
For the documentation about fopen, fread,strchr, you could refer to the HP or C function references.
Hope this will help you.
Assuming you are reading from a data file for the parameters, just use a custom seperator. Comma is the default, but you can define it to be whatever you want. Whenever I have a comma in the variable data I tend to use a pipe symbol, '|' as a way to distinguish the columns of data in the data file.
Examine your parameter dialog carefully and you will see where to make the change.
