YNAB CSV Export to Ledger

YNAB CSV Export to Ledger is a conversion tool to take a YNAB 4 CSV export and create a plaintext accounting ledger register file.

Introduction

ledger-cli is a command line tool for double-entry accounting based on a plain text file. This application takes a CSV file that was exported from YNAB 4 register and creates a plain text register file.

Although ledger-cli offers a CSV import tool and maintains a list of CSV conversion tools, this tool is specifically designed to import YNAB CSV files. This simplifies the process by asking a few simple questions.

Features

  • Removes duplicate transfer transactions. Since YNAB isn't a double entry accounting system, a transfer appears twice in the register, once for each account. This import tool removes the duplication.
  • Groups split transactions as a single transaction
    • Supports per-line item comments
  • Imports memos as comments
  • Imports accounts as assets or liabilities based on input
  • Internationalization
    • Is able to handle imports from YNAB with various currencies. Tested $, €, and ден
    • Able to import currencies that use commas decimal separators, spaces for thousands separators, etc.
    • Able to parse numbers in any format supported by the dotnet CultureInfo object
  • Able to parse exported CSV from YNAB in both comma separated and tab separated. YNAB decides how to export based on the currency
  • Tag flagged transactions from YNAB as a meta-data tag
  • Optionally imports transaction state flags

Usage

The first step is to export the data from YNAB 4. To do this, click File and then select Export Ctrl+E. Then select Export to CSV. Do not select Export Budget to CSV as that does not include the register, which this tool uses.

Run the application (see installation), it'll ask various questions to import the file.

  • Output file name - This is the name and path of the exported YNAB 4 CSV file. YNAB exports two files, the budget and the register. This tool requires the register.
  • Use Cleared colum - (Default Y) whether or not to use the reconcile feature of YNAB in the export file to set the transaction state flags. If you do not reconcile transactions in YNAB, then you can set this to N so that your transactions in ledger won't all include the ! state flag.
  • Culture - (Default en-US) Use this to specify which culture the numbers and dates will be in. For example, if you are using YNAB with french euros, then set the field to fr-FR. This is used by the tool to parse the amounts and dates.
  • CSV Delimter - (Default ,) YNAB exports the register with comma separated fields, or tab separated fields depending on the culture. If the register csv contains numbers from a culture that separates the decimal component with commas, it'll export the data as tab separated. To specify a tab separated file, press the [Tab] key and then enter.
  • For every account the tool finds, it'll prompt to specify whether the account is an asset or a liability. For example, credit cards are a liability, but a checking account is an asset. The responses are case insensitive. For example, Asset and asset both are will work. You can also specify a or l for convenience.
