Dashboard CSV data provide counts with decimal fractions

Where to find the issue

https://www.coronawarn.app/en/analysis/ “Corona-Warn-App (CWA): Key performance indicators”

Describe the issue

All data values in exported data from the Corona-Warn-App (CWA): Key performance indicators page where the fields corresponds to a count of something, and which therefore can only be a whole number, are transmitted with a single decimal place. For example tests_total_cumulated is exported as 71762776.0 instead of the integer value 71762776.

Steps to reproduce

1. Open https://www.coronawarn.app/en/analysis/ in web browser
2. Click on “Export all data”
3. Extract CWA_dashboard_data_yyyy-mm-dd.csv from cwa_all_data.zip
4. Open CWA_dashboard_data_yyyy-mm-dd.csv with text editor
5. Note the first line (containing the field names) starting with update_timestamp,effective_date,infections_published_daily,tests_total_cumulated,
6. Scroll down to the end of the file and note the start of the last full line e.g. "2021-12-16T09:21:49,398",2021-12-15,51301,71762776.0

In the above example

• infections_published_daily is correctly an integer 51301
• tests_total_cumulated is incorrectly transmitted as a real number 71762776.0 with a decimal place. It should be 71762776 without .0 at the end

Suggested change

Remove the decimal place from all of the fields which are counts. That is to say the data belonging to the following fields with names:

• *daily
• *cumulated
• *sum

should be transmitted with no decimal fraction.

Only average values with field names:

• *avg

should be permitted to have decimal fractions in the exported CSV files.

Hi Mike,

I am still in exchange with the responsible people and I have not forgotten about the issue.

As far as I know, it is complicated to remove the decimals because of the different conversion processes.

I’ll stay tuned and let you know if there are any further developments.

Best regards Tobias

Thank you very much for the suggestion. I have forwarded the issue and an adjustment will be made in the near future.

Best regards, Tobias
