Export list data into CSV Form

[TIMAI2]

@Nieves_Joshua

I am currently using sharing then save as text

I do not understand what you mean by this ?

[Nieves_Joshua]

Sorry for the confusion
I try this Code the encounter this error "argument is neither Class nor Type"
but the QR-Code is Generated and no QR-Code in the gallery ....

[Nieves_Joshua]

Sorry sir what I mean is I tried to follow your codes but still no CSV file in my storage device.
I even selected the output in the listpicker.

[TIMAI2]

Did you Add a tag and its values to the tinydb before trying to export?
Was that data in the tinydb (use getValue to check in companion)
Where/how are you looking for your csv file ?

[Nieves_Joshua]

Here sir..

Get Value Tag

@TIMAI2

use the File component Move block

The File component uses / needs a relative path:

Absolute path │ relative path │ full path

something like this (not tested)

but I should do better

[TIMAI2]

My third question was:

Where/how are you looking for your csv file ?

[Nieves_Joshua]

I dont know if my answer is correct.
Where/how am I looking for csv file?
-in my File Manager, storage

Show your blocks (where the csv file is saved).

[TIMAI2]

@Nieves_Joshua

in my File Manager, storage

Does your File Manager allow you to look in the application specific folders of apps ? (e.g. your app)

[Nieves_Joshua]

This is my code and I think it is incomplete.
I can use the Sharing but I can only save Text.
Is there a way to save it as .CSV where I can see the list of data that I had save in CSV file.
Thank you

When I tried this code for generating QR-Code I encounter this error.

@Nieves_Joshua

Not really had a full answer to this one yet ?

@Nieves_Joshua

I can use the Sharing but I can only save Text.

Again, I do not understand what you mean by this ?

in your app: qr code validity in a wider context

I mentioned this earlier in the topic, but you did not respond to this.

Will your qr codes only be used in your app? It is most likely they will have no validity in a wider context, and will most probably not qualify or be seen as valid covid passports country wide or internationally.

In Europe and many other countries around the world, a standard qr code format, with base45 encoding, is used to generate valid covid passport qr codes, which can only be generated by government agencies. The data can be read using an extension:

Extension. COVID-19. Decode QR Green Pass. Certificate. Encode/Decode QR

Hello friends, here an extension to decode the COVID-19 EU QR Certificate, also called QR Green Pass. It's a demo, have a Toast. I have published this extension on my website in Spanish and I adapt it to this Community. 0.- About EU QR Certificate. Green Pass. In some European countries, those vaccinated against COVID-19 (also those who have been recovered and those who have undergone a test) are given a QR code called the EU QR Certificate or QR Green Pass. In this QR code you will find d…

I see you are now using @Juan_Antonio 's extension.

Hopefully you understood this message:

This extension decodes a "QR Green Pass".
Encoding requires a legal certificate, that is why it is called "COVID Certificate", in addition to other types of encoding Base45, zlib, cose, cbor...

With this extension you cannot create a valid "QR Green Pass"

[Nieves_Joshua]

Yes Sir TIMAI2 But I dont know how to save using image.
I must solved the "Generate QR-Code and Save to Picture" first before I proceed further in saving listpicker files or DB files into CSV. i'll get back to this topic for the meantime Ill closed this to avoid confusion. Thank you Sir @TIMAI2
