How to read CSV files

Here's a quick example of converting a CSV file.

Say we have downloaded checking.csv from a bank for the first time:

"Date","Note","Amount"
"2012/3/22","DEPOSIT","50.00"
"2012/3/23","TRANSFER TO SAVINGS","-10.00"

We could create checking.csv.rules containing:

# skip the first CSV line (headings)
skip 1

# use the first three fields in each CSV record as transaction date, description and amount respectively
fields   date, description, amount

# prepend $ to CSV amounts
currency $

# always set the first account to assets:bank:checking
account1 assets:bank:checking

# if the CSV record contains ‘SAVINGS’, set the second account to assets:bank:savings
# (if not set, it will be expenses:unknown or income:unknown)
if ~ SAVINGS
 account2 assets:bank:savings

CSV files in the manual describes the syntax.

Now hledger can read this CSV file:

$ hledger -f checking.csv print
using conversion rules file checking.csv.rules
2012/03/22 DEPOSIT
    income:unknown             $-50.00
    assets:bank:checking        $50.00

2012/03/23 TRANSFER TO SAVINGS
    assets:bank:savings         $10.00
    assets:bank:checking       $-10.00

We might save this output as checking.journal, and/or merge it (manually) into the main journal file.
