## Running

There are some configurable parameters when running in the command line. It is even possible to automatically get the latest source file and parse into a new JSON. Options are:

• –fetch Enables downloading of a new data file from B3 server. It will consider this file when parsing. This is disabled by default, try to parse a local file under files folder.

• –b3_file FILENAME Specifies the local data file location. Make sure that it is UTF-8 encoded, other encoding may not work.

• –json_file JSONNAME Specifies the name of the resulting JSON file. Defaults to files/stocks_data.json.

Important to note that –fetch and –b3_file are mutually exclusive.

### Example

1. Running to fetch a new file and customize the resulting JSON

> b3tojson –fetch –json_file files/beautiful_file.json

2. Using a local file to parse

> b3tojson –b3_file files/my_local_file.txt
