Hi Members,

I have a requirement in Power Automate, that I need to export more than 50,000 or 100000 data from SharePoint list to Excel.

So for that, I started creating a flow, as per below mentioned steps:

Manually Trigger a flow
Send an HTTP request to SharePoint
1. uri = _api/web/lists/getbytitle('BO')/items
Parse JSON
1. Content: body(Send_an_http_request_to_SharePoint)
2. Schema:

{
    "type": "object",
    "properties": {
        "d": {
            "type": "object",
            "properties": {
                "results": {
                    "type": "array",
                    "items": {
                        "type": "object",
                        "properties": {
                            "Title": {
                                "type": "string"
                            },
                            "field_1": {
                                "type": "string"
                            },
                            "field_2": {
                                "type": "integer"
                            },
                            "field_3": {
                                "type": "string"
                            },
                            "field_4": {
                                "type": "string"
                            },
                            "field_5": {
                                "type": "integer"
                            },
                            "field_6": {
                                "type": "string"
                            },
                            "field_7": {
                                "type": "string"
                            },
                            "field_8": {
                                "type": "string"
                            },
                            "Modified": {
                                "type": "string"
                            },
                            "ID": {
                                "type": "integer"
                            },
                            "Created": {
                                "type": "string"
                            },
                            "AuthorId": {
                                "type": "integer"
                            },
                            "EditorId": {
                                "type": "integer"
                            },
                            "OData__UIVersionString": {
                                "type": "string"
                            },
                            "Attachments": {
                                "type": "boolean"
                            },
                            "GUID": {
                                "type": "string"
                            }
                        }
                    }
                }
            }
        }
    }
}

4. Create CSV Table: Result = body('parse_json')?['d']?['results']

But I am facing an error as: "The error indicates that the 'from' property in the 'Create CSV table' action is receiving a value of type 'Null', which means it is not getting the expected array of items. This is likely caused by the previous action, where the 'results' property from the parsed JSON is not being populated correctly. To resolve this, you should check if the 'body' of the HTTP request to SharePoint is returning the expected data structure, particularly if the 'd' and 'results' properties are present and contain an array."

Please help me out.

Thanks in advance!

Hi,

Since I can only see the action names and not the outputs, you should check whether the output from the Parse JSON action is not null. To do this, you can insert a Compose action to inspect the data and verify that the expression you used in the Create CSV action is returning the expected results.
By using the Compose action, you can confirm if the values you’re working with are correct before passing them into the Create CSV action. This will help you ensure that the expression is working as expected.

When I use the compose action, we can see the fields are extracting. But still in the create csv table facing an error. Please help me out with the flow, how can I achieve it to extract more than 10,000 or 100000 data.

Hi,

Can you share the output's of those actions like Send HTTP request to Sharepoint and Parse Json?

Also, show what you are passing in create csv table as well, you can hide any sensitive data
