File sales tax from an Excel spreadsheet.

Excel is common because finance teams already use it to adjust exports, reconcile channels, and prepare state-ready summaries. The upside is flexibility. The downside is inconsistency.

Where Excel Fits

Excel usually sits between raw exports and the final filing view.

Many businesses do not file straight from platform data. They export, reconcile, adjust for marketplace exclusions, and organize tax figures in Excel first. AtomicTax can work with that, as long as the workbook is readable and the logic is clear.

Platform exports saved as `.xlsx`
Adjusted summary tabs maintained by finance or bookkeepers
Monthly workbooks already used in the close process
