When I try Talend with simple JSON data it could able to convert the JSON data to table format. But when comes to nested JSON data I am not sure how to do it. Can someone help me on this?

How can you get XML out of a Data Factory?
Great there is an XML format but this is only a source ... not a sink
So how can ADF write XML output?
I've looked around and there have been suggestions of using external services, but I'd like to keep it all "in Data Factory"
e.g. I could knock together an Azure Function, which could take JSON, and convert it to XML, using an example like so
But how can I then get ADF to, e.g. to this XML to a File System ?
No, this is not possible.
If you just want to copy, then use binary format is ok. But if you are trying to let ADF output XML, it is not possible.(As the document you mentioned told.)
I am trying utilise Django REST APIs to insert data into the database, instead of the direct write. I've been able to read JSON data using the tRESTClient component but I am not too sure about the insertion/POST. Could someone point me to the components (and relation) that I should use?
The current job that I have is mostly:
Read data from raw file -> tMap -> DB
and I wish to do something like:
Read data from raw file -> tMap -> (pass on data to REST endpoint via POST)
Used the tRestClient component after my tMap and I could see the records getting inserted into the DB but all of them are without any data. Strangely nowhere I was asked to specify the JASON tree. The number of records getting inserted are equal to rows being read from raw file so at least something is right. But I couldn't locate the menu/options to specify which data element read from the raw file should tag to which JASON element.
How do I specify the data to JSON mapping?
PS: I realise that this might not be the most efficient way to ingest data but that's what the business wants since it brings in an additional layer of control.
Actually, I need to create a transformation which will read the JSON file from the system directory and rename the JSON fields(keys) based on the metadata inputs. Finally, write the modified JSON into '.js' file using JSON output step. This conversion must be done using the ETL Metadata Injection step.
Since I am new to Pentaho Data Integration tool, can anyone help me with the sample '.ktr' files for the above scenario.
Thanks in advance.
The same use case is on the Pentaho official documentation here, except it does it with Excel files rather than JSON objects.
Now, the Metadata Injection Step requires the development of a rather sophisticated machinery. And json, it is rather simple to build with a simple javascript. So, where do you get the "dictionary" (source field name -> target field name) from?
What I want :
I want to use Auto Completion of Text field in my App.As my data is coming from the web service, I want to perform the "Auto Completion" with the JSON Response.
What I Know :
I know that first I have to fetch data from the web service. Then I need to parse it and fill the Array with that parsed data and then I can use that array to perform Auto Completion.
Problem :
I don't know how to send the requests to get JSON data for each "prefix" that user types in text field (means I want JSON Data during Typing). I know how to perform "JSON Parsing" and "Auto completion of text fields" independently but no idea regarding "TextField Autocompletion with JSON Response". I tried a lot to find the answer regarding this but i failed. So Please Help me...
I am using the doautocompletetextfield to perform "Text field Auto completion".
Better Suggestion for this problem will be appreciated.
Any Solutions ?
You can use linear searching just like done in the api example or can use NSPredicate for fast searching in your autoCompleteArray.
According to your problem, you will get json data first, then you need to save relevant data from json into some array and then you can use this api to autocomplete the text in text field.
But i am confused about your this statement: "I don't know how to send the requests to get JSON data for each "prefix" that user types in text field."
1) Do you want to get json data from web service during typing?
2) Or you want to fetch data from json dictionary during typing?
If you want to go with option (1), i think it would be bad way to solve the problem.
And if you want to go with option (2) then you need to parse json and extract data of your interest and save it in an array. And then do autocomplete on the basis of the contents of that array.
hi friend
can any one tell me that i have web server there i have create the database for store some value for registration form the value was save in webserver this is working good
but now that data coming in json format and now i have fetch json value and save in to the local database which is same as the webserverdata base both the side ssame table and same colume name is there how can i do this
and how to writ the query for this sitution help me
Various JSON parsers exist for objective c. You'll have to pass the data to a library or to javascript in a webview to extract it. Here is a google library:

If you need help with saving the data, I say with no snideness whatsoever that you should read the manual:
