File Filter
Rows and values never reach an AI model

Change a spreadsheet by describing what you want

Upload an Excel or CSV file, describe the change in plain language, and download the result. Pick rows, drop columns, sort, deduplicate, clean up, highlight, add formulas — no macros and no pivot tables.

How it works

Three steps, no spreadsheet skills

Every run is recorded, so you can go back and download an earlier result at any time.

  1. 01

    Upload your file

    Drop in a CSV, XLSX or XLS file. If a workbook has several sheets, pick the one you want to work on.

  2. 02

    Describe the change

    Write it the way you would say it out loud — "keep only rows where amount is over 100, and sort by date". There is no formula syntax to learn.

  3. 03

    Download the result

    You get a new workbook with the result, plus a summary of how many rows and how much size changed.

What you can ask for

Far more than filtering

One instruction can pick rows, reshape the columns, clean the values and colour the result — all in the same run.

  • Pick rows by a condition

    Numbers, text, statuses, any combination of AND and OR. Case does not matter.

  • Nothing is ever lost

    The rows that were cut always land on a separate tab. You do not have to ask for it — it happens on its own.

  • Keep only the columns you need

    Drop the extra columns, or go the other way and keep three out of thirty.

  • Rename headers

    Bring column names into your own format without touching a single value.

  • Sort and take the top

    Sort by any column, or take the N largest straight away.

  • Remove duplicates

    By a single column, or by a combination of several.

  • Tidy the data up

    Stray spaces, inconsistent case, empty cells, numbers stored as text.

  • Add a calculated column

    A new column holding a computed value — a difference, a percentage, a share.

  • Highlight what matters

    Colour a whole row or single cells, several rules in different colours, bold text.

  • Split across tabs

    A separate tab per category, each with the set of columns you need.

  • Compute with Excel formulas

    Live formulas rather than frozen numbers: a total under the table, or a formula on every row.

Privacy

Your data stays on our servers

The rows and values in your file are never sent to an AI model. Only the column headers and your instruction leave our infrastructure, and that is enough to build the code that does the work.

  • Only headers and your instruction

    The model sees the column names and what you asked for. It never sees a single row of your data.

  • Everything runs on our own servers

    The generated code is checked and executed on our infrastructure. Your file never goes anywhere else.

  • Deleted automatically

    Uploads and results are removed after 14 days. You can delete any run, or your whole account, sooner.
