Field Mapping is the process of linking the headers in your Excel or CSV file with corresponding Xero fields in SaasAnt Transactions Xero Online. By default, SaasAnt considers the first row of your uploaded file as the header row.
Each header must be mapped to the appropriate Xero field so that SaasAnt can correctly understand and import the data into your Xero account.

How do I map my file?
I don’t understand how mapping works – it seems confusing.
Don’t worry. Field mapping is straightforward when approached step-by-step, and this guide will guide you through the entire process.
Xero fields refer to the specific data input areas in a Xero transaction form (like Invoice, Bill, Payment, etc.). These include fields such as Invoice Date, Customer Name, Account Code, Tax Rate, and others.
The available fields may vary depending on the transaction type you are importing (e.g., Invoice vs. Payment).
You can refer to our import help articles for Xero-specific guidance for each transaction type.

The right side shows the column headers from your uploaded file.

Select the appropriate File Header for each Xero field.
You can hover over any Xero field to view a brief description of what that field means.
This layout helps ensure you're connecting your data correctly to the right fields in Xero.
