Hi @rpa13,

Yes you can convert excel into json format.
Sharing screenshot below for your reference:

Also attaching json file
config - Copy.json (2.4 KB)


I would suggest the following

  1. Read “Sheet” range
  2. Add the sheet range to a collection dictionary
  3. Serialize the collections dictionary to get a json.

Workflow file:

*Note: If you have more sheets, add the activities Read Range and Invoke Method(add in dictionary) inside a loop (For Each) to read each sheet and at the end serialize everything.

Implementation details
  1. Include UiPath.WebAPI.Activities or just Newtonsoft.Json package
    DataTableToJson - Package

  2. Import into sequence file:
    DataTableToJson - Import

  3. Variables used in the sequence file:
    DataTableToJson - VariablesUsed

  4. Invoke Method

    • TargetObject: DictCollections
    • MethodName: Add
    • Parameters:
      DataTableToJson - InvokeMethod AddDictionary Parameters
  5. Invoke Method

    • TargetType: Newtonsoft.Json.JsonConvert
    • MethodName: SerializeObject
    • Parameters
      DataTableToJson - InvokeMethod Serialize Parameters

I share source code in its minimum functional version (It doesn’t require anything additional to run). (8.2 KB)

target-json-format.json (240 Bytes)
here is the json file format must be like this
your workflow give me another format
as i need each product in colum proudcts in sheet to be object with value quantity
like this “1234”:{“quantity”: 1}

target-json-format.json (240 Bytes)
the target json file output

This being the case, you must manipulate the row to convert it into the desired object.

The solution I would give is:

  1. First convert the row to a dictionary of dictionaries (to emulate an object).
  2. Then add it to a list of objects (dictionaries).

There you would have your collection of Sheet1.

If you want to add more columns, you must add them at the time of converting the row to an object (Invoke Method ‘Add to DictRow’).

New Dictionary(Of String, String) From { 
	{"quantity", row("quantity").ToString}, 
	{"column3", row("column3").ToString}, 
	{"column4", row("column4").ToString}

Source code: (8.7 KB)

Likewise, as I said in a previous answer, if you are going to do the same thing for several sheets, you should contain all the object construction inside a loop that goes through all the sheets, and at the end of the construction, serialize.


format.json (238 Bytes)
