Background: I attempted to import a CSV file into a KV Store using v3.3.3 of the Lookup Editor app. One of the fields in the CSV uses 0 to represent false and 1 to represent true. I set the corresponding field as Boolean when I created the KV Store but when I tried to import the data the Boolean field showed "#bad-value". I found that in order to get the CSV to be successfully imported into the KV Store, I had to pre-process the script (using sed) to replace the 1's with "true" (sans quotes) and the 0's with false (again, sans quotes).
Various settings within the Splunk config files use 0 to represent false and 1 to represent true. Would it be possible to have Lookup Editor do the same when importing in to a field that has been typed as "Boolean"?
