Ledger Guesser

Harness the power of machine learning with ledger-cli

experimental but functional.

Install

git clone https://github.com/j3k0/ledger-guesser.git
cd ledger-guesser
npm install

Usage

Training

./ledger-guesser --train JOURNAL_FILE.txt

Will take quite some time (depending on the size of your journal). This will generate files ~/.ledger-guesser-nn-[0-9a-f].json.

Guessing

Once the neural network has been trained, you can make it guess the full ledger entry.

./ledger-guesser PAYEE AMOUNT CURRENCY [DATE]

Example

$ ./ledger-guesser 'GOOGLE GSUITE_ USD10.00' -10.00 USD 2019/05/21

2019/05/21 GOOGLE GSUITE_ USD10.00
  Assets:Bank:Blom:Usd   -10.00 USD
  Expenses:Tools:Gsuite   10.00 USD

Note that you can change the directory where ledger-guesser stores training files by setting the TRAINING_DIR environment variable.

Example: export TRAINING_DIR=~/company-2

Lower-level usage

The ./ledger-guesser script make use of index.js to create 16 different files: 1 for each potential line in the ledger entry.

node index.js" --train journal_file.txt --index=0 will output training output in JSON for the first line of the a ledger entry. (index=1 for the second line, etc).

node index.js --guess training.json PAYEE AMOUNT CURRENCY will output a line of ledger entry.

Example

$ node index.js --train journal.txt --index=0 > line-0.json
$ node index.js --train journal.txt --index=1 > line-1.json
$ node index.js --guess line-0.json 'GOOGLE GSUITE_ USD10.00' -10.00 USD
Assets:Bank:Blom:Usd  -10.00 USD
$ node index.js --guess line-1.json 'GOOGLE GSUITE_ USD10.00' -10.00 USD
Expenses:Tools:Gsuite  10.00 USD

With ledger-autosync

For my usage, I use a forked version of ledger-autosync that uses ledger-guesser for guessing account names. This allows to import full CSV/OFX files and create a pretty accurate output.

The interesting commit is here: https://github.com/j3k0/ledger-autosync/commit/24de64d2d711199b7e0898325aceeedeb09bb596#diff-235eadfde015c04f77e02a6063e19c2cR199

A proper integration is left as an exercice to the user! ;-)
