I previously mentioned piecash will easily import csv transactions. It also creates the account structure in the process.
piecash is a GnuCash compatible python library. It doesn't use GnuCash but creates files that are compatible with GnuCash. piecash is an alternative to the python bindings which are optionally part of GnuCash and use GnuCash. See https://piecash.readthedocs.io/ for details. ---------------------------------------- The example below uses data based on GnuCash Tutorial and Concepts Guide Part II. Managing Personal Finances - https://gnucash.org/viewdoc.phtml?rev=4&lang=C&doc=guide The sample code needs a code folder that must contain `simple_csv_book_creation.py` and `demo.csv`, and a folder named `gnucash_books` at the same level as the code folder. `simple_csv_book_creation.py` must be run from the code folder. D:\demo |------ examples | demo.csv | simple_csv_book_creation.py | |------ gnucash_books Install python Version 3 D:\>pip install piecash D:\demo\examples>python simple_csv_book_creation.py Created: ../gnucash_books/simple_csv.gnucash The file created can be opened in GnuCash.
