automatically converting each CSV record into a transaction. (To
learn about *writing* CSV, see [CSV output](hledger.html#csv-output).)
To instruct hledger how to convert CSV records to transactions, we
must provide a CSV rules file. By default this is named like the CSV
file with a `.rules` extension added. Eg when reading `FILE.csv`,
hledger also looks for `FILE.csv.rules` in the same directory. You can
specify a different rules file with the `--rules-file` option. If a
rules file is not found, hledger will auto-create it with some example
rules, which you'll need to adjust.
We describe each CSV file's format with a corresponding *rules file*.

descriptions. Here's an overview of the CSV rules;
these are described more fully below, after the examples:
------------------------------------------- ---------------------------------------------------
[**`skip`**](#skip) skip one or more header lines or matched CSV records
[**`fields`**](#fields) name CSV fields, assign them to hledger fields
[**field assignment**](#field-assignment) assign a value to one hledger field, with interpolation
[**`if`**](#if) apply some rules to matched CSV records
[**`end`**](#end) stop processing CSV records
[**`date-format`**](#date-format) describe the format of CSV dates
[**`newest-first`**](#newest-first) disambiguate record order when there's only one date
[**`include`**](#include) inline another CSV rules file
------------------------------------------- ---------------------------------------------------
There's also a [Convert CSV files](convert-csv-files.html) tutorial on hledger.org.
# EXAMPLES
Here are some sample hledger CSV rules files. See also the full collection at:\
<https://github.com/simonmichael/hledger/tree/master/examples/csv>
## Basic
At minimum, the rules file must identify the date and amount fields,
and often it also specifies the date format and how many header lines
there are. Here's a typical simple rules file:
there are. Here's a simple CSV file and a rules file for it:
```csv
Date, Description, Id, Amount
12/11/2019, Foo, 123, 10.23
```
<!-- examples/csv/basic.csv.rules -->
```rules
# basic.csv.rules
skip 1
fields date, description, _, amount
date-format %d/%m/%Y
skip 1
```
```shell
$ hledger print -f basic.csv
2019/11/12 Foo
expenses:unknown 10.23
income:unknown -10.23
```
Default account names are chosen, since we didn't set them.
## Bank of Ireland
Here's a CSV with two amount fields (Debit and Credit), and a balance field,
which we can use to add balance assertions, which is not necessary but
provides extra error checking:
```csv
Date,Details,Debit,Credit,Balance
07/12/2012,LODGMENT 529898,,10.0,131.21
07/12/2012,PAYMENT,5,,126
```
<!-- examples/csv/bankofireland-checking.csv.rules -->
```rules
# bankofireland-checking.csv.rules
# skip the header line
skip
# name the csv fields, and assign some of them as journal entry fields
fields date, description, amount-out, amount-in, balance
# We generate balance assertions by assigning to "balance"
# above, but you may sometimes need to remove these because:
#
# - the CSV balance differs from the true balance,
# by up to 0.0000000000005 in my experience
#
# - it is sometimes calculated based on non-chronological ordering,
# eg when multiple transactions clear on the same day
# date is in UK/Ireland format
date-format %d/%m/%Y
# set the currency
currency EUR
# set the base account for all txns
account1 assets:bank:boi:checking
```
```shell
$ hledger -f bankofireland-checking.csv print
2012/12/07 LODGMENT 529898
assets:bank:boi:checking EUR10.0 = EUR131.2
income:unknown EUR-10.0
2012/12/07 PAYMENT
assets:bank:boi:checking EUR-5.0 = EUR126.0
expenses:unknown EUR5.0
```
The balance assertions don't raise an error above, because we're
reading directly from CSV, but they will be checked if these entries
are imported into a journal file.
## Amazon
Here we convert amazon.com order history, and use an if block to
generate a third posting if there's a fee.
(In practice you'd probably get this data from your bank instead,
but it's an example.)
```csv
"Date","Type","To/From","Name","Status","Amount","Fees","Transaction ID"
"Jul 29, 2012","Payment","To","Foo.","Completed","$20.00","$0.00","16000000000000DGLNJPI1P9B8DKPVHL"
"Jul 30, 2012","Payment","To","Adapteva, Inc.","Completed","$25.00","$1.00","17LA58JSKRD4HDGLNJPI1P9B8DKPVHL"
```
<!-- examples/csv/amazon.csv.rules -->
```rules
# amazon.csv.rules
# skip one header line
skip 1
# name the csv fields, and assign the transaction's date, amount and code.
# Avoided the "status" and "amount" hledger field names to prevent confusion.

# combine two fields to make the description

# save the status as a tag

# set the base account for all transactions
account1 assets:amazon
# leave amount1 blank so it can balance the other(s).
# I'm assuming amzamount excludes the fees, don't remember
# set a generic account2
account2 expenses:misc
amount2 %amzamount
# and maybe refine it further:
#include categorisation.rules
# add a third posting for fees, but only if they are non-zero.
# Commas in the data makes counting fields hard, so count from the right instead.
# (Regex translation: "a field containing a non-zero dollar amount,
# immediately before the 1 right-most fields")
if ,\$[1-9][.0-9]+(,[^,]*){1}$
account3 expenses:fees
amount3 %fees
```
```shell
$ hledger -f amazon.csv print
2012/07/29 (16000000000000DGLNJPI1P9B8DKPVHL) To Foo. ; status:Completed
assets:amazon

you'll need to add a date-format rule describing them with a
strptime date parsing pattern, which must parse the CSV date value completely.
Some examples:
