I've been using mint.com for the last couple of years and I've found it to be an invaluable tool for personal (and business) finance management and visualization. After it was acquired by Intuit, I was a bit worried, but it does look like Mint will replace QuickBooks online and not the other way around. However, one thing that I thought surely would come out of the acquisition would be ability to seamlessly trade data between the two applications. My accountant prefers to get my financial data in QuickBooks format and I certainly prefer the ease and intuitiveness of Mint. I always knew that mint allowed exporting transactions into Excel via comma-separated values file (CSV) and I was very surprised to find out that QuickBooks only allows limited Excel import - you cannot import transactions but only lists of vendors and such.
After some poking around, I found out about ability to import transactions into QuickBooks using IIF files. Essentially, these are specially formatted text files that include information about the transaction and account involved. After reading some documentation, I decided to bite the bullet and write a tool to convert transactions exported from mint into IIF, such that they can be imported into QuickBooks.
Welcome ccQuickMint - a tool to convert Mint's transaction export into a format that can be imported into QuickBooks.

How it works:
Step 1: Cut a hole in a box… (sorry, I'm really a 13 year old trapped in a 30 year olds body)
But seriously:
Step1: Export Transactions From Mint to CSV file

Step 2: Feed the CSV File into ccQuickMint via 'Load' button and wait for the Razzle Dazzle
Step 3: Adjust account information (type, description, etc) and select appropriate export options
Step 4: Use ccQuickMint to output transactions into an IIF file via 'Export to IIF' button
Step 5: Import saved IIF file into QuickBooks

Step 6: Profit??
Under the Hood:
IMPORTANT: Please read this section. Here I will outline assumptions that were made and limitations of my implementation.
Account Logic
The tools maps the concept of Mint "Category" to the concept of "Expense Account" in QuickBooks. So when the tool processes a transaction , it uses the account as one side of the transactions (debit or credit) and Mint category as the other side (Debit or Credit).
For Example, a Mint Transaction like:
|
Date |
Description |
Amount |
Type |
Category |
Account |
|
12/17/2010 |
ExxonMobil |
52.02 |
debit |
Gas & Fuel |
Citibank Credit Card |
Would result in a debit to the Citibank Credit Card account and a credit to the Gas & Fuel expense account.
The accounts will be automatically created in QuickBooks (if you check off the appropriate box in ccQuickMint). If the Category contains the word 'income', the account will be created as an income account. Otherwise, by default 'Category' will imply an Expense account. All Mint accounts will default to 'BANK'. Once transactions are loaded into ccQuickMint, you can change the account type (to CCARD for example). Don't forget to click 'Apply'.
There are a couple of problems with this. First and foremost, it fails for things like credit card payments because the category 'credit card payment' does not represent an account but represents an action. A 'credit card payment' action is in fact a transfer from one account to another (i.e. debit to the checking account, and a credit to the credit card account).
Transfer/Credit Card Payment Logic
To mitigate this, ccQuickMint has custom handling of 'credit card payment' and 'transfer' categories. (If you have other transfer style categories you will have to rename them for the time being to either exactly 'transfer' or exactly 'credit card payment'). However, for transfers and CC payments two transactions are needed to be matched together (as opposed to in a typical expense, where a single transaction contains all the needed info). In other words, when ccQuickMint encounters a transaction like:
Date | Description | Amount | Type | Category | Account |
12/21/2010 | Credit Card Payment | 1597 | debit | Credit Card Payment | Checking Account |
It needs to see another transaction like
Date | Description | Amount | Type | Category | Account |
12/23/2010 | Credit Card Payment - Thank you | 1597 | credit | Credit Card Payment | Citibank Credit Card |
Since these transactions do not necessarily follow each other in Mint's export file, this was a tiny bit of a challenge. When ccQuickMint sees a transfer/cc payment transaction, it checks if it already has a counter transaction for the same amount. If it has, all the data are available to create a QuickBooks entry. Otherwise, it stores the transaction until the 2nd part is found.
Since I am making some logical leaps with this amount matching logic, I included a feature to ignore credit card payments and transfers (disabled via checkbox), such that they can be manually entered.
Known Issues
- Multiple IIF Imports: Despite assigning unique IDs to transactions in the IIF file, if you import an IIF file into QuickBooks more than once, all transactions will be duplicated. I feel like this is a QuickBooks issue. As a workaround, you can edit the CSV file exported by Mint and remove transactions that have been already imported.
- If you have more than once Credit Card for the same account (i.e. you and your spouse), Mint shows it as two separate accounts. They both would have the same balance, but different transactions. There is not really a good solution for this. I ended up manually editing Mint's CSV file and changed the account name to be the same for cards that were attached to the same account.
- I've encountered a strange error while importing an IIF file into QuickBooks. I am fairly sure it's an Intuit issue and it happens if you try to import an IIF file while having a report open. Closing all QuickBooks windows (i.e. account registers, reports, etc) prior to import resolves an issue.

- There has been little testing, so hopefully you can report any issues you find and I will keep this list current, so people know what to expect.
Support
Surely there will be issues with this tool. It worked for me, but I wrote it with me in mind. Please send any problems you encounter my way and I will process them in the order of available time.
If you find the tool useful and are interested in keeping updates going, please provide feedback and/or buy me a beer or something. Also, feel free to contact me for any customization requests.
