looks like data returned by getluckysheetfile are different from the format {data} expects in the config
take a look at data they are passing to the sheet in the demo
100% not result of getluckysheetfile()
1) luckysheet.transToCellData(luckysheet.getLuckysheetfile()[0].data)
[0] here means the first sheet in the document
[0] here means the first sheet in the document
2) var rawData = luckysheet.getluckysheetfile()
3) rawData.celldata = result of (1)
You can now dump rawData.data as they are useless to store
JSON.stringify rawData, send that to server and when you load back, JSON.parse retrieved object
works
