Solved: Adding Multiple JSON files by Query Editor

jonasdedual23 · ‎09-17-2023

Hi There

I have the following situation. I want to add about 1000 shares to a power bi dataset by using API from eodhd. All the API request strings are saved in a seperate Table:

Here an example:

https://eodhd.com/api/eod/AAPL.US?api_token=demo&fmt=json&period=d

I then create a new query with below code(In below code I only add the colum date to make it more simple. In final version there will be more columns):

let
    Source = SYMBOLS_Price,
    AddCustomColumns = Table.AddColumn(Source, "Custom", each
        let
            ApiUrl = [Column1], 
            Source = Json.Document(Web.Contents(ApiUrl)),
            TableFromList = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
            ExpandedColumn = Table.ExpandRecordColumn(TableFromList, "Column1", {"date"}, {"date"}),
            ChangedType = Table.TransformColumnTypes(ExpandedColumn, {{"date", type date} })
        in
            ChangedType
    ),
    #"Expanded Custom" = Table.ExpandTableColumn(AddCustomColumns, "Custom", {"date"}, {"Custom.date"})
in
    #"Expanded Custom"

This is working fine and I get what I want:

However when doing the same with fundament data and replacing in aboce code SYMBOLS_Price with "SYMBOLS_Cash_Flow", I'll get an Error message:

Expression.Error: We cannot convert a value of type Record to type List.
Details:
Value=[Record]
Type=[Type]

A sample of an API string would be:

https://eodhd.com/api/fundamentals/AAPL.US?api_token=demo&filter=Financials::Cash_Flow::quarterly

The only difference that I have found is the structure of the JSON format:

SYMBOLS_Price has:

[
   {
      "date":"1999-11-18",
      "open":42.8579,
      "high":47.0966,
      "low":37.6772,
      "close":40.2676,
      "adjusted_close":24.428,
      "volume":44733602
   }
]

SYMBOLS_Cash_Flow has:

{
"2023-07-31":{
"date":"2023-07-31",
"filing_date":"2023-08-31",
"currency_symbol":"USD",
......
}
}

I suspect that "2023-07-31": is the issue here. However I have no Idea how to adress this issue.

Any Help is highly apreciated.

kind Regards

Jonas

Finally I have found a workaround for my Problem.

I am using now the code below:

let
    SYMBOLS_LIST = {SYMBOLS_LIST{0}, SYMBOLS_LIST{1}, SYMBOLS_LIST{2}}, 


    AddData = List.Accumulate(SYMBOLS_LIST, Table.FromRecords({}), (table, symbol) =>
        let
            ApiUrl = "https://eodhd.com/api/fundamentals",
            QueryParameters = [
                RelativePath = symbol,
                Query = [
                    api_token = "API-Token",
                    filter = "Financials::Cash_Flow::quarterly"
                ]
            ],
            Source = Json.Document(Web.Contents(ApiUrl, QueryParameters)),
            RecordList = Record.ToList(Source),
            TableFromRecord = Table.FromRecords(RecordList),
            Final = Table.AddColumn(TableFromRecord, "SymbolColumn", each symbol)
        in
            Table.Combine({table, Final})
    ),

    FinalTable = Table.Distinct(AddData),
    #"Sorted Rows" = Table.Sort(FinalTable,{{"SymbolColumn", Order.Ascending}, {"date", Order.Descending}, {"filing_date", Order.Descending}}),
    #"Reordered Columns" = Table.ReorderColumns(#"Sorted Rows",{"date", "filing_date", "SymbolColumn", "currency_symbol", "investments", "changeToLiabilities", "totalCashflowsFromInvestingActivities", "netBorrowings", "totalCashFromFinancingActivities", "changeToOperatingActivities", "netIncome", "changeInCash", "beginPeriodCashFlow", "endPeriodCashFlow", "totalCashFromOperatingActivities", "issuanceOfCapitalStock", "depreciation", "otherCashflowsFromInvestingActivities", "dividendsPaid", "changeToInventory", "changeToAccountReceivables", "salePurchaseOfStock", "otherCashflowsFromFinancingActivities", "changeToNetincome", "capitalExpenditures", "changeReceivables", "cashFlowsOtherOperating", "exchangeRateChanges", "cashAndCashEquivalentsChanges", "changeInWorkingCapital", "stockBasedCompensation", "otherNonCa**bleep**ems", "freeCashFlow"}) // Optional: Entfernen von Duplikaten, falls erforderlich
in
    #"Reordered Columns"

I guess there would be a simpleer way of coding but above works for me.

The List "SYMBOLS_LIST " contains the following Entries:

A.US

AA.US

AAPL.US

I get then the below result(not all columns / Rows in this sample:

31.08.2023	A.US	USD	-89000000
26.05.2023	A.US	USD	-77000000
03.03.2023	A.US	USD	-104000000
21.12.2022	A.US	USD	-3000000
27.07.2023	AA.US	USD	-120000000
04.05.2023	AA.US	USD	-102000000
23.02.2023	AA.US	USD	-171000000
27.10.2022	AA.US	USD	-138000000
04.08.2023	AAPL.US	USD	437000000
05.05.2023	AAPL.US	USD	2319000000
03.02.2023	AAPL.US	USD	2483000000
28.10.2022	AAPL.US	USD	2806000000

Not sure what you mean by that:

"Please provide sample data that fully covers your issue."

The sample data can be directly downloaded from here:

https://eodhd.com/api/fundamentals/AAPL.US?api_token=demo&filter=Financials::Cash_Flow::quarterly

Please note that api_token=demo only works for the Symbol AAPL.US However structure of each Symbol is the same.

Here is the Table of SYMBOLS_Cash_Flow: (I had to remove APIKEY)

Column1

https://eodhd.com/api/fundamentals/AAPL.US?api_token=demo&filter=Financials::Cash_Flow::quarterly

https://eodhd.com/api/fundamentals/AAA.US?api_token=APIKEY&filter=Financials::Cash_Flow::quarterly

Cash_Flow the transform is very simple

let
    Source = Json.Document(Web.Contents("https://eodhd.com/api/fundamentals",[RelativePath="AAPL.US", Query=[api_token="demo" ,filter="Financials::Cash_Flow::quarterly"]])),
    #"Converted to List" = Record.ToList(Source),
    #"Converted to Table" = Table.FromRecords(#"Converted to List")
in
    #"Converted to Table"

I don't think the Price is included in the API response.

As the message says - lists are identified via { } and records are identified via [ ] . you need to parse them differently.

Please provide sample data that fully covers your issue.
Please show the expected outcome based on the sample data you provided.
