saving output file in nicegui

[studyprogresslili]

Question

Hi everyone,
I have written a code in nicegui. The output is a file that allows the user to enter data. Some keys on the file allow the user to perform calculations and the results appear at the determined places.
I want to save this output file including the entered data and results.
Is there any possibility in nicequi to save this file with the existing format along with the input data and the results?
Thanks

You can simply get the value from each element and save the data to json/yaml/pdf or what ever Python library you want.

Do you mean I import the data using a YAML file during coding with niceQUI, rather than importing it after the output is received?

Here is an example of my code.
The output allows the user to enter data and receive a pass or fail result.
What is the best way to save this output page with the user data and the results?

from nicegui import ui

def calculate_results():      
    setpoint = float(setpoint_input.value)
    measured = float(measured_input.value)

    deviation = abs((measured - setpoint) / setpoint) * 100  

    deviation_label.set_text(f'{deviation:.1f}% (<5%)' if deviation < 5 else f'{deviation:.1f}% (>5%)')  

    if deviation < 5:
        pass_fail_result.set_text("PASS")
        pass_fail_result.style('color: green;')
    else:
        pass_fail_result.set_text("FAIL")
        pass_fail_result.style('color: red;')

with ui.column():
        
    with ui.card().style():
       
        with ui.row():
            ui.label('setpoint')
            setpoint_input = ui.input(value='', on_change=calculate_results)
            ui.label('Measured')
            measured_input = ui.input(value='', on_change=calculate_results)
            deviation_label = ui.label('')

    with ui.card().style():
        pass_fail_result = ui.label('PASS/FAIL').style("font-weight: bold;")
        ui.button('Calculate', on_click=calculate_results)

ui.run()

@studyprogresslili Which format are you planning to use for the export?

Here is a related discussion about exporting the generated page as image or PDF: #2025

There's also an example about generating PDFs from within a NiceGUI app: https://github.com/zauberzeug/nicegui/tree/main/examples/generate_pdf

Thanks all.
I could solve the problem more or less.
I added a box beside the output values on the output results page.
Values and their names are transferred into the box when the user enters a value.
The box can be saved as a PDF.
