Data Format

File format information is taken from YNAB's online documentation for CSV import files.

YNAB requires one of two formats for the CSV import file.

Option One

This format uses separate fields for outflows and inflows.

Date	Payee	Memo	Outflow	Inflow
06/22/2021	Payee 1	Memo	100.00
06/23/2021	Payee 2	Memo		500.00

Each field is separated by a comma, so it's important that every field is present in each line—even if your transactions don't fill every field. Always include the "Date,Payee,Memo,Outflow,Inflow" header line at the very top. Any field can be left blank except the date.

Option Two

This format has one small variation—the amount is one field instead of two. Outflows are identified by a negative sign in the Amount field.

Date	Payee	Memo	Amount
06/22/2021	Payee 1	Memo	-100.00
06/22/2021	Payee 2	Memo	500.00
