What the file needs to look like

It needs a header row: a column naming the product (sku, product, title and similar), then one column per day of units sold. A day column is counted or dated.

Counted is d1, d2, d3 …, or day 1, dy 1, wk 1, week 1. A plain number on its own is not enough: a column named just 1001 is a product code as often as it is a day, so it is refused rather than added up.

Dated is 2024-05-01, 05/01/2024, 1-May or May 1, each of those also accepted with a time on the end, as in 2024-05-01 00:00:00, which is what a spreadsheet pivot usually exports.

Every day needs its own column: a name that appears twice is refused rather than added up twice. A column it cannot place by name is refused, never guessed at.

Why this is free, and what it leaves out

Dead stock is the one number you can get from a sales export alone, so it is the one this page gives you. Cash tied up needs a unit cost. Days at zero needs a daily stock level, which almost no export carries. Anything claiming all three from a sales file is guessing at two of them.
