How can I generate/export the node.csv and edge.csv files in the current version of Joern?
I'm currently replicating the workflow from a research paper which requires exporting node.csv and edge.csv. It seems that older versions of Joern supported exporting these files. Is this functionality still available in the current version? Thank you!
We offer a neo4jcsv export https://github.com/joernio/joern/blob/master/joern-cli/src/main/scala/io/joern/joerncli/JoernExport.scala#L109 Check if that helps.

Thank you very much for your response！As I'm new to this field, I'm still getting familiar with Joern and Java. I have a basic question that I'd like to ask for guidance:
When I previously used Joern, I would simply clone the joern-cli folder, extract it, and run it using ./joern in that directory. Now that I've cloned the entire Joern project repository, how should I properly execute the JoernParse.scala method you provided in this project folder?
I understand this might be a very simple (or even trivial) question, but as a beginner, it has genuinely confused me for some time. I would greatly appreciate your expert advice on this matter. Thank you kindly for your support!
Just like the ./joern start script there is also one for ./joern-export.
Run ./joern-export --help for guidance.

There are two folders containing joern-export:
https://github.com/joernio/joern/blob/master/joern-export
https://github.com/joernio/joern/blob/master/joern-cli/src/main/scala/io/joern/joerncli/JoernExport.scala
Should I run it in the former directory? But when I downloaded and tried to run it, the system reported 'no such file or directory', even though I can clearly see it when I run 'ls'. What could be the reason for this?"
Simply download the latest release at https://github.com/joernio/joern/releases, unpack the zip and run the joern-export script in the resulting folder.

Thank you very much for your answer! Following your method, I successfully generated the CSV files. However, when processing the example file x42.c, nearly 100 different CSV files were generated in the folder, such as:
edges_ARGUMENT_cypher edges_ARGUMENT_data edges_ARGUMENT_header
nodes_LOCAL_cypher nodes_LOCAL_data nodes_LOCAL_header and others... Could you please explain what these files represent?Or, when processing a CPG , is there a method to generate a comprehensive file containing all node properties (such as ID, type, etc.) in the graph? Thank you very much!"
