Reading an excel file on Google App Engine can be done using the following steps:
- Create a Google Cloud Storage (GCS) bucket to store the spreadsheet.
To create a GCS bucket, go to the Google Cloud Console, click Storage > Browser, and click Create bucket.
- Upload the spreadsheet file to the created GCS bucket.
- Download the spreadsheet file from GCS to the Google App Engine instance.
To do this, use the Google Cloud Storage Client Library for Python (gsutil).
- Parse the spreadsheet file.
You can use libraries such as xlrd or openpyxl to parse and read the spreadsheet file into memory.
- Perform processing or transactions as needed.
- Clean up afterwards by deleting the spreadsheet file.
These are the steps to read an Excel file on Google App Engine. If you need more detailed information on how to use the libraries and other processes involved, refer to the official Google App Engine documentation (https://cloud.google.com/appengine/docs/standard/python/).
