The short answer
The John Lewis Partnership Card (NewDay) file has 4 columns, dates written as DD/MM/YYYY and one amount column where a positive value is money out. YNAB wants a CSV with the columns Date,Payee,Memo,Outflow,Inflow. So the date is rewritten as YYYY-MM-DD, the amount is split into Outflow and Inflow, and the text columns are moved as in the table below.

What the John Lewis Partnership Card (NewDay) CSV looks like
- Country: United Kingdom.
- Account type: credit card.
- Header row: yes, one row before the first transaction.
- Columns: 4, separated by commas.
- Date format: DD/MM/YYYY, for example 04/03/2024 (the source writes it as %d/%m/%Y).
- Amounts: one amount column where a positive value is money out. Evidence for the direction: it is inferred from the role the open-source importer gives the column; no sample row confirms it.
- Header text: the source gives column positions and meanings only, not the header names.
Note kept with this layout in the profile data: File name in the source: recentTransactions.csv. Cards issued before 2022 used another layout (Date,Payee,Outflow,skip with dates like 01-Nov-2019), listed in the same source.
What YNAB accepts
- File type: CSV (the vendor calls it the recommended and preferred format); QFX, OFX and QIF are also accepted.
- Header row: optional; the import preview has a "No header row" option.
- Required columns: Date, Outflow, Inflow.
- Optional columns: Payee, Memo.
- Amounts: Two positive columns: money out in Outflow, money in in Inflow. A single signed amount column is also accepted: the user selects the same column for both Inflow and Outflow in the import preview, and YNAB reads positive and negative values from it. The preview has a "Swap Inflow and Outflow" option.
- Dates: not stated on the page; the columns and their reading are confirmed in the import preview.
| YNAB column | Required by YNAB | Filled from the John Lewis Partnership Card (NewDay) file |
|---|---|---|
| Date | required | column 1 |
| Payee | optional | column 2 |
| Memo | optional | column 3 |
| Outflow | required | column 4, rows that are money out |
| Inflow | required | column 4, rows that are money in |
From the vendor's help page: "Select that same Amount column for both the Inflow and Outflow fields in the import dropdowns. You don't need to reformat your file or split it into two columns first—YNAB reads positive and negative values from a single column."

Pitfalls for John Lewis Partnership Card (NewDay) to YNAB
Dates
- The date must be reordered. The bank file is written day first, then month, then year (DD/MM/YYYY, for example 04/03/2024). The YNAB file is written year first, then month, then day (YYYY-MM-DD, for example 2024-03-04).
- YNAB on dates: not stated on the page; the columns and their reading are confirmed in the import preview. The converter writes year-month-day because it cannot be misread as day/month or month/day. The vendor page does not list accepted date formats, so the user must check the dates in YNAB's preview before importing.
Amounts and their direction
- Sign flip: in this bank file a positive amount is money out. Positive values go to Outflow and negative values go to Inflow, without their minus sign. Sorting them the usual way round would book every purchase as income.
- YNAB's own rule: Two positive columns: money out in Outflow, money in in Inflow. A single signed amount column is also accepted: the user selects the same column for both Inflow and Outflow in the import preview, and YNAB reads positive and negative values from it. The preview has a "Swap Inflow and Outflow" option.
- How sure the direction is: it is inferred from the role the open-source importer gives the column; no sample row confirms it. Compare two rows you recognise with the preview before importing; the converter has a switch that flips the sign of every amount.
Other YNAB import rules
- The vendor states it is no longer necessary to format a CSV file before uploading it; columns are matched to fields with dropdown menus after upload.
Before and after: an invented example
Invented sample data. These four rows were made up for this page. They are not from a real John Lewis Partnership Card (NewDay) export and hold no real account, name or balance.
The source gives column positions only, so the headings below are the column number and what the column holds, not the bank's header text.
| 1: transaction date | 2: description | 3: memo or note | 4: amount |
|---|---|---|---|
| 04/03/2024 | COFFEE CORNER MAIN ST | Card purchase | 4.50 |
| 05/03/2024 | PAYROLL EXAMPLE CO | Salary March | -2500.00 |
| 07/03/2024 | RENT MARCH | Standing order | 1234.56 |
| 11/03/2024 | REFUND EXAMPLE SHOP | Refund | -15.25 |
| Date | Payee | Memo | Outflow | Inflow |
|---|---|---|---|---|
| 2024-03-04 | COFFEE CORNER MAIN ST | Card purchase | 4.50 | |

Do it by hand in a spreadsheet, free
These steps need no tool from this site. The cell references follow the column positions of the profile above; if your spreadsheet uses semicolons between formula arguments, replace the commas.
- Open the John Lewis Partnership Card (NewDay) CSV in a spreadsheet program through its import dialog. Set the date column (column 1) to Text so the program does not reinterpret it, and leave the amount columns as numbers.
- Row 1 is the header and the transactions start in row 2.
- Date: rewrite column A from DD/MM/YYYY to YYYY-MM-DD (04/03/2024 becomes 2024-03-04). In a new column, for the first transaction:
=MID(A2,7,4)&"-"&MID(A2,4,2)&"-"&MID(A2,1,2)This formula reads the date by character position, so it only works while the dates are text and every date has a two-digit day and month. Fill it down. - Amounts: in this file a positive value is money out. Outflow:
=IF(D2>0,D2,"")Inflow:=IF(D2>0,"",-D2) - Text columns: fill Payee (from column 2); Memo (from column 3). Where several bank columns feed one column, join them with a separator such as " - ".
- Apply YNAB's own rules from its help page: The vendor states it is no longer necessary to format a CSV file before uploading it; columns are matched to fields with dropdown menus after upload.
- Keep only the new columns, put the header row Date,Payee,Memo,Outflow,Inflow on top, save the sheet as a comma-separated CSV, and compare the dates, the direction of the amounts and the number of rows with your statement in YNAB's import preview.

Where this layout comes from
No bank supplied or approved this layout. It was copied on 5 October 2026 from a public open-source importer file kept by volunteers: bank2ynab/bank2ynab, file bank2ynab/data/bank2ynab.conf
The lines used from the source: [UK John Lewis Partnership Card (NewDay Format)] Source Filename Pattern = recentTransactions|\d{8} ; Input Columns = Date,Payee,Memo,Outflow ; Header Rows = 1 ; Date Format = %d/%m/%Y
The YNAB rules come from the vendor's own help pages: support.ynab.com/en_us/file-based-import-a-guide-Bkj4Sszyo (named as text, not linked), support.ynab.com/en_us/formatting-a-csv-file-an-overview-BJvczkuRq (named as text, not linked). The official page was fetched and read on the checked date.
Bank formats change. Banks alter their CSV exports without notice and vendors change their import rules, so this mapping can be out of date. If the preview looks wrong, use the manual column mapper.
