What goes in, and what comes out

Sample of a real kind of mess: mixed date formats, no categories, blank rows, amounts as text.

The output

A spreadsheet you can actually work from

One messy file becomes a clean, multi-tab workbook: sales, expenses, invoices, customers and products each get their own sheet, with consistent dates, proper amounts, and records linked by ID. Export to Excel and go.

The cleanup

What it sorts out for you

Splits one file into proper books

Separates customers, suppliers, products, invoices, expenses, payments, inventory and more out of a single jumbled sheet into their own clean tabs.

Reads any layout

Handles pivot tables, cross-tabs and line-item rows, and groups scattered lines back into the right invoice or record.

Matches up the columns

Works out what each column means even when it's renamed, reordered, or labelled oddly ("Sales", "Purchases", and the like).

Standardizes dates & amounts

Every date to one format; every amount, currency symbols, commas, stored-as-text and all, to a real number.

Categorizes and fills gaps

Assigns sensible categories, marks income vs expense, and generates IDs for records that are missing them.

Flags what to double-check

Marks ambiguous rows for your review instead of quietly guessing, then hands it all back as a formatted, multi-tab Excel workbook.
