Online financial aggregators are great for getting transactions from all of your accounts into one place, but the accounting tools they provide are pretty minimal. I'm a Mint user, and I like the idea of letting Mint manage the connection to my bank, but I need to get the data into a real accounting package: GnuCash.

Mint provides the data in CSV format. So far I have been able to convert that data into QIF. The file format for QIF was simple enough that I was able to write my own conversion tool.

However, with QIF I can only import data from one account at a time. Ideally I would like to be able to download transactions from all of my accounts at once. Here's a sample of Mint data with a few accounts in it:

Date,Description,Original Description,Amount,Transaction Type,Category,Account Name,Labels,Notes
3/29/2014,BART,BART-POWELL QPS 5104646979 CA 94102 US C_OTHERTRAVEL,20,debit,Public Transportation,CapitolOne Visa,,
3/28/2014,Student Loan Payment,MY STUDENT LOAN LENDER,40,debit,Student Loan,Checking,,
3/28/2014,Check 995525,Check Paid #995525,64,debit,Check,Checking,,
3/28/2014,Mortgage,MY MORTGAGE COMPANY,1.95,debit,Credit Card Payment,OtherChecking,,
3/28/2014,Paycheck,MY EMPLOYER,1,000,000.00,credit,Paycheck,Checking,,

It would be nice if I could take this file and process it once and output a file that GnuCash could then import into the correct accounts. I was working with an OFX converter, but I'm not clear that OFX can combine data from multiple accounts into a single file due to the requirement to have a ledger balance line.

Is this a reasonable way to try to move data from Mint to GnuCash?

You can fetch accounts and transactions using intuit(Mint) API. This requires to apply for dev. account.

  • This is a good answer if you have some programming know-how, and don't want to write the conversion more than once :) – trapezoid Dec 26 '17 at 22:25

I am also looking to do exactly what you describe.
I just came across mintcash and it looks like it has the functionality.
Granted this solution requires some python knowledge, no code generation should be required.
It uses two other libraries:mintapi and piecash

I just attempted to do this but it seems that mintapi currently has a login issue that is literally two days old at this writing due to mint changing some authentication related calls. Hopefully someone will patch it soon.

GnuCash has a CSV import option!

  • I should have mentioned in my original post: the CSV import process in GnuCash was way too combersome. Every time you import you have to redo the column and data-type matching for each field. – alwayssummer Dec 28 '17 at 1:27
