Hello,
I have complex JSON events ingested as *.log files. I have issues (or couldn't do) with extracting fields from this files/events. Any help on how to extract Key-Value pairs from these events would be highly appreciated. One sample event is given below. Thank you so much.

Hi @SplunkDash,
I hint to try to use spath, because regexes is a very hard way to extract fields, infact you have to create many extractions for each field, e.g. the following:
| rex "\"workplace\" : \"(?<workplace>[^\"]+)\""Ciao.

Hi @SplunkDash,
you don't ned to extract inline, you could also extract and save extraction, but try to use spath.
Ciao.

Hello @gcusello,
How can I save the extraction for later use without defining it as inline or transformation or macro?

Thank you so much again. But from the web interface (UI), I can see only 2 ways we can save field extraction INLINE and Transformations. If I use +Extract New Fields or Extract Fields, it goes to INLINE (regular expression) or Field Transformations (Delimiters) option. No where is allowed me to use spath. Is there anything I am missing? Thank you so much again.

Hello @gcusello,
Thank you so much again. But from Web interface (UI), I can see only 2 ways we can save field extraction INLINE or Transformations. If I use the option at the bottom of the left most column (where fields are listing) "+Extract New Fields", still not letting me to use spath option like as follow. Is there anything I am missing here? Please guide me if possible. Thank you!
