如何使用 python 脚本自动将数据集导出到 Power BI 文件

Question

I have a power BI report that uses SQL server and the data set in xlsx format. I need to export this to dataset when ever I open powerbi file so that it automatically detects the dataset file which is present with the same name and display it using python script.

So is there any way possible to automate this procedure.

Answer 1

Yes, that's possible. In Power BI Desktop, select File > Options and settings > Options > Python scripting . The Python script options page appears, and just choose the python environment you are using.

To run your Python Script in Power BI Desktop:

In the Home ribbon, select Get data > Other.

Select Other > Python script as shown in the following image:

Select Connect . Your local latest installed Python version is selected as your Python engine. Copy your script into the Python script dialog box that appears.

And for reading Excel data. I would use openpyxl . Here is a small demo:

def xlsx_reader(): 
    data = []
    file_exist = os.path.exists('demo.xlsx')
    if file_exist:
        wb = openpyxl.load_workbook('demo.xlsx')
        wb1 = wb['demo']
        
        data.append(wb1['A1'].value)
    return data

Here is the document for openpyxl.
