Negative number is not recognized as a number

Thanks for this awesome plugin! I use it to get my swarm check-ins from a google sheet. Sometimes the coordinate are negative and it results in the error and consequently in omitting these columns at all.

googleSheetSwarmCheckinsRow.longitude:

• type: number
  value: 50.36813591
• type: string
  value: '-6.121681532'
  googleSheetSwarmCheckinsRow.latitude:
• type: number
  value: 15.17281175
• type: string
  value: '-0.1278404805'

I ran into this bug also with pulling in Coordinates. My Solution was to wrap coordinates in quotes before POSTing and then remove when pulling them back in. Thats the only solution I could come up with until a fix is made.
