Getting and cleaning data

The url to make API calls is https://api.crunchbase.com/v3.1/csv_export/csv_export.tar.gz?user_key=[API KEY GOES HERE]

API key (premium) is located at E:\projects\crunchbase3

The command line (bash script) to get the data and extract the data (1.9gb) is at E:\projects\crunchbase3\get_data.sh

Alternatively, we can download and extract directly using windows command prompt by typing the following commands

curl -O https://api.crunchbase.com/v3.1/csv_export/csv_export.tar.gz?user_key=[API key goes here] \
      
tar -xvf csv_export.tar.gz_user_key=[API key goes here].

The sql script get_data.sql from last year is copied to the current Crunchbase3 directory. However, two databases are very different now and adjustments are necessary. To keep track of the data type from each csv file used to copy to sql tables, a file get_type.py is included in E:\projects\crunchbase3. This python script will print the first 5 rows of every data frame in the current directory.

Hiep will continue fixing the get_data.sql script on 03/22/2019.
