Script em python para carregar os arquivos de cnpj dos dados públicos da Receita Federal em MYSQL.

Overview

cnpj-mysql

Script em python para carregar os arquivos de cnpj dos dados públicos da Receita Federal em MYSQL.

Dados públicos de cnpj no site da Receita:

A partir de 2021 os dados da Receita Federal estão disponíveis no link https://www.gov.br/receitafederal/pt-br/assuntos/orientacao-tributaria/cadastros/consultas/dados-publicos-cnpj (ou http://200.152.38.155/CNPJ/) em formato csv zipado.

Pré-requisitos:

Python 3.8;
Bibliotecas pandas, dask, sqlalchemy e pymysql.

Utilizando o script:

Baixe todos os arquivos zipados do site da Receita e salve na pasta "dados-publicos-zip".
O download no site da Receita é lento, pode demorar várias horas. Sugiro utilizar um gerenciador de downloads.

Crie uma pasta com o nome "dados-publicos".

No servidor MYSQL, crie um database, por exemplo, cnpj.
Especifique os parâmetros no começo do script:
dbname = 'cnpj'
username = 'root'
password = ''
host = '127.0.0.1'

Para iniciar esse script, em um console DOS digite
python dados_cnpj_para_mysql.py

A execução durou cerca de 5hs em um notebook i7 de 8a geração.
