Extract options.json data¶

CVM data is downloaded using the START_DATE and END_DATE parameters in the CONFIG key defined in options.json.

Name	Description
`START_DATE`	Required parameter (YYYY-MM-DD).
`END_DATE`	Optional parameter (YYYY-MM-DD). If provided, data is downloaded up to this date; otherwise, the current date is used.

Note

If END_DATE is not present in options.json during execution, the program automatically updates the file by setting END_DATE to the current date.

Using this information, the program iterates through all months between START_DATE and END_DATE.

Download Status¶

After downloading archives from CVM in a month-year schema, the program stores the .zip files in their respective directories on /data.

Status	Description
200	A `.zip` archive is successfully returned for the requested month.
404	Link not found. The program logs the corresponding month/year with issues.

Extraction Status¶

After extracting the archives from the .zip directory, the program creates a new directory containing all monthly .csv data on /data.

Status	Description
Success	Archives were successfully extracted.
Failed	No archives were found in the `CVM/ZIP` directory.
