Hey, thanks so much for your help. That works great - how can I set it up so the target currency is always NZD so I can just type in :100USD or :10GBP and it will output $167 and $22.55 respectively, no currency unit? I tried ask ChatGPT to do it but for some reason it couldn't, kept getting :ERR or :1ERR for 3 digit numbers...thanks

  - regex: :(?P<amount>\d+(?:\.\d+)?)(?P<src>[A-Z]{3})
    replace: ${{output}}
    vars:
      - name: output
        type: shell
        params:
          cmd: |
            rate=$(curl -s "https://open.er-api.com/v6/latest/{{src}}" | jq -r ".rates.NZD")
            if [ "$rate" = "null" ] || [ -z "$rate" ]; then
              echo "ERR"
            else
              printf "%.2f" "$(echo "{{amount}} * $rate" | bc -l)"
            fi

Thanks. I made a slight modification so it would accept lower case currency does as well:

  - regex: :(?P<amount>\d+(?:\.\d+)?)(?P<src>[a-zA-Z]{3})
    replace: ${{output}}
    vars:
      - name: output
        type: shell
        params:
          cmd: |
            src_upper=$(echo "{{src}}" | tr '[:lower:]' '[:upper:]')
            rate=$(curl -s "https://open.er-api.com/v6/latest/$src_upper" | jq -r ".rates.NZD")
            if [ "$rate" = "null" ] || [ -z "$rate" ]; then
              echo "ERR"
            else
              printf "%.2f" "$(echo "{{amount}} * $rate" | bc -l)"
            fi
