import JSON file but data is strange

I am using Backendless 4.0, and try to import JSON file from local computer.

However, after I got msg from the server, the data table is strange.

I had 186 objects, but they show only 32 null objects.

Is there any issue of import Json file? Please check

Does this file was created from 3.x or 4.x backendless?

But backendless creates only csv files, how do you get this file?

URL

I converted this from csv by Python Pandas.

We do not support such scenario. You can export to csv( change it) then import to another application, but only csv file. We support json files only for Parse export files.

There is a number of issues with this file:

1. It starts from ',' but should be column name, I have added this num(INT) at the beginning

2. there are duplicate column names 'address' and 'name', so I have changed it to name2(STRING(36)) and address2(STRING(72))

so the first line should be

num(INT),created(DATETIME),affiliated(BOOLEAN),hits(INT),petSize(STRING(144)),images(TEXT),reviewAverage(DOUBLE),updated(DATETIME),advertising(BOOLEAN),objectId(STRING_ID),serviceCategory(STRING(72)),serviceablePet(STRING(500)),desc(STRING(500)),name(STRING(36)),isAdvertising(BOOLEAN),verified(BOOLEAN),note(STRING(144)),reviewCount(DOUBLE),website(STRING(144)),headerImageUrl(TEXT),priceInfo(STRING(288)),emailAddress(UNKNOWN),contact(STRING(36)),isAffiliated(BOOLEAN),operationTime(STRING(288)),subtitle(STRING(500)),ownerId(STRING(36)),isVerified(BOOLEAN),address(STRING(72)),location__GeoPoint__bcklsFK__ONE_TO_ONE,name2(STRING(36)),address2(STRING(72)),cafe_Urls(TEXT)

Hmm can u check my data table? Result table seems weird bcs it seems like everything was perfect but it show only partial data such as objectId, created, updated.

However, when I try to add a property in schema such as 'hits', they say it is already existing.

This is my Result class data table from code generation.

import UIKit

class Result: NSObject {

var objectId : String?

var ownerId : String?

var updated : Date?

var created : Date?

}

Hi Ken,

Please provide your application ID.

URL

KenChoi ● 3 weeks ago

Now it looks fine.

However, there was quite big gap between the notification by mail and the time which the job has done. If u still need app ID, plz let me know.

Sometimes the notifications are delayed a bit, though it shouldn't be more than a few minutes.

URL

KenChoi ● 3 weeks ago

Yeap understood but it was quite weird at the first time haha

(I mean notification was too fast)
