.Sh NAME
.Nm pta_import
.Nd print pta journal entries from bank CSV file input
.Sh SYNOPSIS
.Nm pta_import
.Fl I Ar bankFormat
.Op Ar file
.Sh DESCRIPTION
The
.Nm
utility converts lines from a CSV
.Ar file
generated by a financial
institution into journal entries used by
.Xr pta 1 .
.Pp
If the
.Ar file
argument is omitted, standard input is read instead.
.Pp
.Ar bankFormat
is exactly one of
.Bl -tag -width Ds
.It capital_one_credit
.It chase_credit
.It optum_hsa
.El
.Pp
and corresponds to an existing
.Qq import_bankFormat.txt
file in the current directory.
.Sh FILES
.Bl -tag -width Ds
.It Pa ./import_capital_one_credit.txt
.It Pa ./import_chase_credit.txt
.It Pa ./import_optum_hsa.txt
.El
.Pp
These files contain the header that the financial institution uses, the
account number from
.Pa ./accounts.txt
used by this account, as well as patterns used to map transactions to
the correct account and booking identifier.
.Ss Defining the account number
Each file must contain one line beginning with
.Qq ACCOUNT
and is followed by whitespace and then an account number.
The account number corresponds to the account in
.Pa ./accounts.txt
for the imported account.
.Ss Patterns in the import_bankFormat.txt files
Each file contains lines of the form
.Pp
.Ar selector account_number booking_identifier
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
Add journal entries to a journal file using a CSV file generated by
a financial institution:
.Pp
.Dl "$ pta_import -I chase_credit chasedownload.csv >> journal.txt"
.Ss A sample credit card purchase
Suppose a line in the
.Pa chasedownload.csv
file looks like
.Pp
.Dl "10/26/2020,10/26/2020,example.com*asldfkj,Shopping,Sale,-17.07"
.Pp
If the line matching the
.Qq Shopping
category in the user's
.Pa ./import_chase_credit.txt
file is
.Pp
.Dl ,,,Shopping,,, 9996 SHOP
.Pp
then the
.Qq Shopping
category defined by Chase is mapped to the user's
.Qq SHOP
booking identifier, and the user's account for shopping
expenses is defined as
.Qq 9996
in their
.Pa ./accounts.txt .
.Pp
We further assume in this example that the user has edited
.Pa ./import_chase_credit.txt
so that the line beginning with
.Qq ACCOUNT
contains the liability account they have defined for their Chase card
in
.Pa ./accounts.txt
.Pp
In this example,
.Pa ./import_chase_credit.txt
contains
.Dl ACCOUNT 3234
.Pp
Then
.Nm
prints
.Pp
.Dl "20201026 SHOP 9996 3234 17.07 example.com*asldfkj"
.Ss A sample credit card payment
.Dl "10/27/2020,10/27/2020,Payment Thank You - Web,,Payment,1653.42"
.Pp
Suppose the user's
.Pa ./import_chase_credit.txt
file contains
.Pp
.Dl ,,,,Payment,, 1700 PAY
.Pp
which matches Chase's payment category to the user's asset account
.Qq 1700
used to pay off the credit card.
Then
.Nm
prints
.Pp
.Dl "20201027 PAY 3234 1700 1653.2 Payment Thank You - Web"
.Ss Account numbers in the import_bankFormat.txt files
For example, if
.Pa ./import_capital_one_credit.txt
contains
.Pp
.Dl ACCOUNT 1293
.Pp
then there must be a corresponding entry in
.Pa ./accounts.txt
such as
.Dl 1293 L Capital One credit card
.Pp
The description
.Qq Capital One credit card
may vary, but in this example, the account numbers
.Qq 1293
match, and the account type is
.Qq L
to indicate that it is a liability account.
.Ss Patterns in the import_bankFormat.txt files
Suppose
.Dl ,,,Automotive,,, 1111 AUTO
.Pp
is a sample entry in the
.Pa ./import_chase_credit.txt
file which uses headers of the form
.Pp
.Dl Transaction Date,Post Date,Description,Category,Type,Amount
.Pp
Then this
.Ar selector
ignores the transaction date, post date, description, type, and amount.
It matches the
.Qq Automotive
category and maps transactions to account
.Qq 1111
defined in
.Pa ./accounts.txt
with the
.Qq Auto
booking identifier.
.Ss A complete example
Suppose
.Pa ./accounts.txt
is given by
.Bd -literal

.Sh BUGS
Currently,
.Nm
has the following limitations:
.Bl -dash
.It
Pattern recognition in the
.Pa import_bankFormat.txt
files is under continued development.
.It
The only defined import formats are for Chase credit cards,
Capital One credit cards, and Optum Health Savings Accounts.
.It
Note that the first pattern match wins in
.Pa ./import_bankFormat.txt .
In the complete example above, we put the line containing
.Qq Dr. Sally Sue
before the line matching the
.Qq Health & Wellness
category because we wanted to override the
.Qq Health & Wellness
category, and use the
.Qq Dental expenses
account instead.
