Delete columns from an Excel file online

Deleting thirty columns by hand to keep three is the kind of work that invites a mis-click. Name the ones you want to keep and everything else goes.

The instruction to paste

Example instruction

Keep every row, but only the Region, Product and Amount columns

How it works

  1. 01

    Upload the file — .xlsx, .xls or .csv, up to 100 MB.

  2. 02

    Paste the instruction, changing the column names to the ones in your own file.

  3. 03

    Download the result. Whatever was cut comes back on a separate tab, so nothing is lost.

Other ways to ask

The instruction is read as a sentence, not filled into a form. These all work on the same file.

  • Remove the Notes and Order ID columns, keep everything else

  • Keep only the columns whose name contains Amount, plus Region

The rows and values in your file are never sent to an AI model — only the column headers and your instruction ever leave our servers.

Questions

Is it better to list what to keep or what to remove?

Whichever is shorter. Both work, and either way the columns come back in the order you named them.

Does the row order change?

No. Dropping columns leaves the rows exactly as they were unless you also ask for sorting.

What if a column name has a typo in my file?

Use the name as it actually appears in the header row. If nothing matches, the run comes back with an error rather than quietly dropping the wrong column.
