Please share the process of adding an .xlsx file to a Lookup list in Splunk Enterprise. Thank you a bunch.
First, you will need to open you .xlsx file in Excel and save it as CSV.
Then settings -> lookups -> Lookup Table File -> New Lookup Table File and upload your CSV file.
Now to combine your new lookup table file, by appending the new to the bottom of the current:
| inputlookup new_lookup.csv
| outputlookup append=t current_lookup
Which will append the entries of the csv you just uploaded to the bottom of your current CSV.
