Convert from FarPoint.Win.Spread.FpSpread to XLSX

Hi,

I’ve got all my data in a database, stored as a FarPoint.Win.Spread.FpSpread XML string, used by a FPSpread5 control. However, we are now developing another page using SpreadJS, which requires data in either a JSON format or as an XLSX. Is there any way to programmatically convert between these formats at runtime?

Thanks,
James
