Export NuBank's NuConta statements as an OFX file.
Easiest way is using Docker:
docker run --rm -it -e NU_CPF=xxxxx -e NU_PWD=xxxxx -v $PWD:/tmp caarlos0/nuofx
NU_CPF
should be your CPF, numbers only;
NU_PWD
should be your NuBank password.
It should display a QR Code. With your phone, open the NuBank app, go to "Perfil" > "Acesso pelo site", scan it, and then press enter on the terminal window.
It should generate a extrato_nuconta.ofx
file on your current directory,
which you can import on any software that can speaks OFX.
