Reckon automagically converts CSV files for use with the command-line accounting tool Ledger. It also helps you to select the correct accounts associated with the CSV data using Bayesian machine learning.
Assuming you have Ruby and Rubygems installed on your system, simply run
gem install --user reckon
First, login to your bank and export your transaction data as a CSV file.
To see how the CSV parses:
reckon -f bank.csv -p
If your CSV file has a header on the first line, include
To convert to ledger format and label everything, do:
reckon -f bank.csv -o output.dat
To have reckon learn from an existing ledger file, provide it with -l:
reckon -f bank.csv -l 2010.dat -o output.dat

If you find CSV files that it can't parse, send me examples or pull requests!
You can run reckon in a non-interactive mode. To guess the accounts reckon can use an existing ledger file or a token file with keywords.
reckon --unattended -a Checking -l 2010.dat -f bank.csv -o ledger.dat
reckon --unattended -a Checking --account-tokens tokens.yaml -f bank.csv -o ledger.dat
In unattended mode, you can use STDIN to read your csv data, by specifying
- as the argument to
csv_file_generator | reckon --unattended -a Checking -l 2010.dat -o ledger.dat -f -
The account tokens file provides a way to teach reckon about what tokens are associated with an account. As an example, this
Expenses: Bank: - 'ING Direct Deposit'
Would tokenize to 'ING', 'Direct' and 'Deposit'. The matcher would then suggest matches to transactions that included those tokens. (ex 'Chase Direct Deposit')
Here's an example of
Income: Salary: - 'LÖN' - 'Salary' Expenses: Bank: - 'Comission' - 'MasterCard' Rent: - '0011223344' # Landlord bank number Hosting: - /hosting/i # This regexp will catch descriptions such as WebHosting or filehosting '[Internal:Transfer]': # Virtual account - '4433221100' # Your own account number
Reckon will use
Expenses:Unknown if it can't match a transaction to an account.
You can override these names with the
If, in the above example, you'd prefer to match any transaction that contains the string 'ING Direct Deposit' you have to use a regex:
Expenses: Bank: - /ING Direct Deposit/

Patches/Pull Requests Process
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history.
- (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
Reckon has integration test located in
spec/integration. These are integration and regression tests for reckon.
Run all the tests:
Run a single test
Add a new integration test
Each test has it's own directory, which you can add any files you want, but the following files are required:
test_args- arguments to add to the reckon command to test against, can specify
-f input.csv, etc
output.ledger- the expected ledger file output
If the result of running reckon with
test_args does not match
output.ledger, then the test fails.
Most tests will specify
--unattended, otherwise reckon prompts for keyboard input.
The convention is to use
input.csv as the input file, and
tokens.yml as the tokens file, but it is not required.
