Opendata plugin not opening spreadsheet

[nick-tallguy]

What steps will reproduce the problem?

1. Install Opendata plugin
2. From JOSM, file / open, and select .ods or any format of spreadsheet

What is the expected result? Spreadsheet opens as new data layer in josm

What happens instead? Error report appears on JOSM screen

Please provide any additional information below. Attach a screenshot if possible. - On the same laptop I booted into Windows 7 and then installed new josm from fresh download of .exe from site. Fresh install of java - from oracle site. Same result - unable to open spreadsheet.

I've been trying for 2 days - sometimes the data appears, but is obviously distorted - instead of the points appearing as a roughly even 'round' shape, they appear as a column. I have used this spreadsheet before to input data, but this was on and around the 21/06/2016 and presumably both my java & josm files are new versions.
