How to parse the British Pound £ sign for currency fields?

[splunkuser_uk]

Hi,

I'm relatively new to Splunk and trying to ingest a cav of transactions in GBP in the format £123.45. I have these in a CSV and ideally want them formatted as currency so that I can analyze in Splunk. When the CSV is ingested the fields are displayed as a string not recognizing the £ sign - I've tried various convert options including (auto) and num but not having much luck.

Assuming as per your comments if string £1,838.38 is coming in currency field as \xA31,838.38 then how about trying this:

1. Ensure currency has no commas to start with (if any)
2. Extract everything after \xA3 from currency field into a new field myCurrency
3. Format back myCurrency to use the £ symbol as a string.

Try below search which shall give you the results needed as stated above.

your base query to return your currency field
 | rex field=currency mode=sed "s/,//g"
 | rex field=currency "A3(?<myCurrency>.*)"
 | fieldformat myCurrency ="£".tostring(myCurrency , "commas") 
 | stats sum(myCurrency )

Hope it helps. Below is the sample makeresults command i used to verify it was working.

How about trying this and see if it works out, assuming string is coming in currency field as £ 42 or £ 42.0 or £42 :

your base query to return your currency field
| rex field=currency "£\s*(?<myCurrency>.*)"
| fieldformat myCurency="£".tostring(myCurrency, "commas")

Hi - thanks for your reply. I tried your suggestion but not having much luck. The problem is the fields in the CSV which contain a currency amount i.e the figure £1,838.38 are being ingested as \xA31,838.38 - the £ symbol is ingested as \xA3 rather than a "£"
