export spreadsheet as text/csv using drive v3 gives 500 internal error

With file as the file ID, http as the http object that you've authorized against you can download a file with:

from apiclient.http
import HttpRequest
def postproc( * args):
   return args[1]
data = HttpRequest(http = http,
   postproc = postproc,
   uri = 'https://docs.google.com/feeds/download/spreadsheets/Export?key=%s&exportFormat=csv' % file,
   headers = {}).execute()

data here is a bytes object that contains your CSV. You can open it something like:

import io
lines = io.TextIOWrapper(io.BytesIO(data), encoding = 'utf-8', errors = 'replace')
for line in lines:
   #Do whatever

Here is an snippet of an implementation of Exponential Backoff from the first link:

ExponentialBackOff backoff = ExponentialBackOff.builder()
   .setInitialIntervalMillis(500)
   .setMaxElapsedTimeMillis(900000)
   .setMaxIntervalMillis(6000)
   .setMultiplier(1.5)
   .setRandomizationFactor(0.5)
   .build();
request.setUnsuccessfulResponseHandler(new HttpBackOffUnsuccessfulResponseHandler(backoff));

Power Apps Export To Excel As A CSV File,If you have any questions or feedback about Power Apps Export To Excel As A CSV File please leave a message in the comments section below. You can post using your email address and are not required to create an account to join the discussion.,In this article I will show you how to use Power Apps to export a file to Excel. ,Thank you Matthew, really good job, im need to implement this in my app, but in the line: “Set( varCSVFile, PowerAppsToExcel.Run(varCars).linkoutput );“, what is the value of this varCars and when this variable was set?

In this article I will show you how to use Power Apps to export a file to Excel.

Download The CSV File And Open In Excel

Put this code in the OnSelect property of the button. The JSON function converts table data, whether from a datasource or from a collection, into text formatted as a JSON.

Set(
   varJSONCars,
   JSON(
      ShowColumns(
         FirstN('Car Sales Inventory', 3),
         "year",
         "make",
         "model",
         "color",
         "location",
         "cost"
      ),
      JSONFormat.IndentFour
   )
)

Then insert a label beside the button and put this code in the Text property.

varJSONCars

Click the generate from sample button and copy + paste the the JSON we created in Power Apps earlier.
A new document library called Export Data must added in SharePoint before selecting it in the create file step.
The Flow will not create a new file if a CSV with the same name already exists. We can make sure this doesn’t happen by adding a timestamp to the end. Here’s the flow expression you should use.

formatDateTime(utcNow(), 'yyyyMMddhhmmss')

4. We want to encode the CSV file in UTF-8 format so it can handle special characters (accented letters, currency symbols, etc). For example, I had a problem where the Euro symbol (€) was not appearing correctly in my CSV file. To solve the issue, use this code. The 3 character prefix in-front of the body(‘Create_CSV_table) identifies the format to Power Automate as UTF-8.

concat(uriComponentToString('%EF%BB%BF'), body('Create_CSV_table'))
