A desktop app, not a chatbot
Neaten cleans the messy export and remembers how. When the new one arrives with a column renamed or missing, it stops and shows you what changed, instead of quietly writing a spreadsheet full of blanks.
Next month’s export arrives with a column renamed, and the saved cleanup stops and asks — rather than writing a spreadsheet full of blanks.
What it fixes
Every month the same report arrives in a slightly different shape. Neaten reads them all, works out which column is which, and writes one file in one convention.
Real values from three example exports. The right-hand column is what Neaten wrote from them.
What it finds
Every problem it finds, with the number of cells affected and an example from your own data.

It refuses to guess
Neaten will not decide for you. A date column read the wrong way round is the kind of mistake nobody finds until the quarter closes.
01/02/2026
It marks the column and converts nothing until you have decided.
Identifiers survive
Open a CSV of invoice numbers in a spreadsheet and 004182 becomes 4182. The zeros are gone, nothing matches anything any more, and nobody warned you. Neaten keeps them as they were.
Flagged when it reads the file, written as text when it writes one. Long numeric references are kept the same way, before anything rounds them.
Opened in a spreadsheet
Same column, same four rows, from the example exports.
Written by Neaten
Kept as text, so a spreadsheet has nothing to reinterpret.
The part that pays for itself
When the cleanup is right, save it: the steps, the column matching, the order, every decision you made. Next month you drop in the new export and press Run.
If a column has been renamed, Neaten tells you which one, offers the match it thinks is right with a confidence figure, and waits. If a column a step needs is gone, the recipe stops — rather than running eight of its nine steps and handing you a file that looks finished.
You do not have to build the recipe at all. Hand Neaten a spreadsheet that is already right and it reads the shape — column names and their order, date and number formats, the spellings you use, how wide your references are padded — and that becomes the recipe.
And then it runs
The recipe reads your clean file once and becomes a set of column rules. When the next export lands it is matched against them and repaired in place — and anything the rules do not settle is left exactly as it was written, for you to decide.
Nothing is uploaded. The pass runs on your own machine, on your own copy.
01/02/2026 — the first of February, or the second of January? Nothing else in the column settles it, so it is left exactly as it was written.
Measured, not claimed
A 52 MB export of 500,000 rows and twelve columns, opened, inspected, cleaned with a nine-step recipe and written back out as Excel. The whole journey, on one laptop.

Questions
Neaten compares it against what the saved cleanup expects. If a column has been renamed it tells you which one, offers the column it thinks replaces it with a confidence figure, and waits for you to confirm — then remembers your answer. If a column a step depends on is missing, the recipe stops rather than writing blanks.
For a one-off, use Excel — you will be finished before this has downloaded. Power Query is powerful, but it is a skill, and whoever wrote the query usually ends up the only person who can maintain it. Neaten is for the cleanup you have already done four times. It shows the steps in plain words anyone can open, and when next month renames a column, it tells you.
A chatbot handles the first file well. Next month you describe the whole job again, and it cannot tell you that a column it used last time is missing — it will hand you something confident and wrong. Neaten saves the cleanup as steps and re-runs them, so the same file gives the same answer twice.
It opens messy CSV and Excel exports, tells you what is wrong with them, lets you fix it while showing you every change, combines several files into one, and writes a clean workbook. Then it saves the whole cleanup so you can run it again next month on the new file.
CSV, TSV and Excel workbooks. It detects the separator and the text encoding for you, including the ones that make Excel show  in the first cell. It exports to Excel or CSV.
No. There is no Neaten server to upload them to. Files are read, changed and written on your own computer, and the published build has no telemetry — not disabled, absent. Check it with a network monitor if you like.
Never. An export writes a new file and leaves the one you started from exactly as it was. Neaten refuses to overwrite an existing file rather than asking a question you might answer too quickly.
