Index csv files with grouped fields?

[kjell_ml]

Hi

I'm using Universal forwarder and trying to consume a complex csv file. Usually this works OK by configuring props.conf correctly on the forwarder. However, this CSV file is quite complex, with many Grouped Field. "{ }" to be used for encapsulating outer most list and "[]" for internal lists.
Every internal list within {} or [] will be comma separated.

Is this possible to achieve? I mean to get the naming of the header fields correct? 

Since the header fields will change depending on which groups or lists have data.

I have a good documentation of the csv file format, but haven't found any ways to make props.conf handle these grouped fields and lists.....

Example data would be helpful, but I suspect the file is more complex than Splunk can handle. Splunk expects all CSV rows to have the same set of fields.
Consider creating a scripted input to ingest that file.

Hi

Here's an example, I have anonymized the data and broken it up on separate lines where the internal groups and lists occur: (Inside the [] brackets there can be data or not, depending on type of transactions. This is what messes up the header_field naming)
