Fuel-card statement to fuel ledger

Open the transaction export from your fuel card. Each row goes into one bucket for its jurisdiction and unit, and the rows are added up and compared with the total gallons and dollars printed on the statement, which you type. Gallons are kept to 3 decimals as whole thousandths.

How it works

  1. Open the statement export. Drop the fuel-card transaction file (.csv or .xlsx). It is read in the browser.
  2. Check the column mapping. Date, jurisdiction, location, gallons, amount, unit, and card or driver are matched from the header words and can be changed. When the jurisdiction column is blank, the two-letter code at the end of a location such as Amarillo, TX is used.
  3. Type the statement totals. Type the total gallons and total dollars printed on the statement so the rows can be tied to them.
  4. Review and export. The ledger by jurisdiction, the ledger by jurisdiction and unit, and the rows with no jurisdiction are shown with the verification certificate. Download Excel or CSV, or print.

Worked example

A made-up statement with six rows. The statement prints totals of 1,680.000 gallons and $5,853.46.

By jurisdiction: NM 299.500 gallons, $1,063.23; OK 400.500 gallons, $1,385.73; TX 900.000 gallons, $3,136.50. One row (80.000 gallons, $268.00) names no jurisdiction and is listed separately. 1,600.000 + 80.000 = 1,680.000 gallons and $5,585.46 + $268.00 = $5,853.46, the totals typed from the statement.

The example uses made-up names and numbers.

Questions

Which fuel-card layouts does it read?

Any .csv or .xlsx with a header row and one row per transaction. Layouts differ between card programs, so the tool does not assume one: it matches header words, shows its choices, and every column can be changed. When gallons cannot be found, the page says so and links to a form for requesting support for that format.

What happens to a row with no jurisdiction?

It stays in the totals, so the statement still ties, and it is listed on its own with its date, location, unit, gallons, and amount. It is not put into any jurisdiction.

Does it handle reversals?

Yes. A row with negative gallons or a negative amount is added as written, so a purchase and its reversal net to zero in their bucket.
