Boy, were those underbid … there’s no way even at $250 due to the complexity involved and the time required to deal with that complexity in attempting to export all the Connections data out as a flat CSV file would be fair. If someone did win and build it, they lost their shirt, hope they do not have a family to feed!
That complexity is why I have not done it myself. Trying to export Connections data as a flat CSV file would be the same as trying to export WordPress data as a CSV file … which is why their export is XML (sort of).
With all that said … I am planning on including a CSV Export in the free core plugin, they’ll be caveats to the exported data. What exactly those caveats will be at this point I do not know but I;m sure they’ll be very similar to the caveats in the script I linked to.
