I'm wanting to pass json format file into a CDT and ultimately into data store using the Write to Datastore Smart Service.
What's the function I need to write as per below so that I can make this work ? Can't work out how to get from json into Dictionary or List format which seems to be required ?

stuartt0002 Can you explain the configuration you did here to push data into the database?
The basic answer is already there. What exactly are you looking for?
I'm a newcomer to the Appian platform, and I need guidance on uploading a .json file using a file upload component. The goal is to incorporate the file's data into the database. Here's a sample .json format:
{
"page.name" : "Home page", "page.nav.title" : "Appian community", "page.nav.button" : "Discuss"}
Could you provide a concise explanation on how can I go about achieving this task?
That's a nice challenge for a newcomer.
To be able to help you, I need to understand what you already learned. So, which of the following things do you already know?
- Store a uploaded file in a folder in Appian
- Create a record and store data to it
- Do all of the above in a process model
- Calling a record type constructor to create a new data structure
- Local variables in expressions
- Plugins
I did a similar challenge that involved importing Excel data into a database using a plugin (Excel Tools) and a smart service (“import excel to database”). I used concepts you mentioned, except for “- calling a record type constructor for creating a new data structure.”
OK. You need the plugin "Text File Utilities".
Then:
- Upload the file
- Then, in an expression with the uploaded file as a rule input
- load the JSON from the file (plugin function)
- convert it into an Appian dictionary using fromJSON()
- map the data to your record type (https://docs.appian.com/suite/help/23.4/reference-records.html#use-a-record-type-constructor)
- the record data is the output of the expression
- call this expression in a script task and store the output in a process variable.
- write the record
