Excel has no watermark feature at all, which means there is no watermark object to remove and no image for a remover to clean. What gets called one is always one of three things somebody placed: a sheet background, a picture parked in the page header, or a floating object sitting on the sheet. Each is deleted inside Excel, and each route takes about four clicks.
That is why an image-cleaning tool is the wrong instrument here rather than a weaker one. A remover works on pixels that were composited together in a picture. A spreadsheet is not a picture: the mark is a property of the document's page setup, and the data underneath it was never painted over.
Below: how to tell which of the three you have, the route for each, and the same question in PowerPoint, where the mechanism is different again.
Which of the three you are looking at
The tell is where the mark appears and whether it moves with the cells. A background sits behind everything and does not scroll away from the grid. A header picture only exists in the printed layout, so it is invisible in the normal view and appears the moment you switch views. A floating object behaves like a shape: it can be selected, dragged, and it sits above or below the grid depending on where it was placed.
- Repeating behind the whole grid, visible while you work. That is a sheet background.
- Only visible in Page Layout or Print Preview, usually centred and faint. That is a picture inside the header.
- Selectable with a click, sits on top of cells, may be WordArt or a logo. That is an ordinary object on the sheet.
Route one: the sheet background
Page Layout → Delete Background. That is the whole of it. The background is a single workbook-level setting, so there is one of them per sheet rather than one per page, and deleting it leaves the cells and their formatting exactly as they were. Worth knowing before you look for it in the print settings: a background is not printed by default, so a file can carry one that never appears on paper.
Route two: the picture in the header
This one hides, which is why it defeats people. Switch to View → Page Layout, then Insert → Header & Footer, and look at the header strip. What you are hunting is a short code rather than a picture: &[Picture]. Delete that code and the mark is gone.
Two details save a second attempt. A large image can cover the code that produced it, so click into each of the three header sections in turn until you find the one holding it. And the header is per-sheet, so a workbook with several sheets may need the same deletion repeated on each of them.
Route three: a floating object
Home → Find & Select → Go to Special → Objects → OK, then press Delete. This selects every object on the sheet at once, which is the point and also the warning: pictures, charts placed as objects, buttons and shapes go with it. If the sheet carries anything you need, select the mark by clicking it instead and delete that one alone.
WordArt is the usual culprit here, because it is the closest thing Excel has to a stamp: text at an angle, semi-transparent, sitting over the data. It is still just an object, and it still goes with Delete.
PowerPoint is a different container, same idea
A PowerPoint watermark behaves the way most people expect a watermark to behave, because slides repeat. The mark that shows up on every slide is normally a shape or picture placed on the slide master: View → Slide Master, select the object on the master layout, delete it, then Close Master View. Every slide built on that layout loses it at once, which is why editing slides one by one is the slow way round.
The exception is a mark placed on an individual slide rather than the master. That one survives the master edit, and it is found by clicking it on the slide that carries it. Both cases are document objects, so neither is a job for a tool that edits pixels.
When the file stops being a file you can edit
Two situations change the answer. The first is a screenshot: once a sheet is captured as a picture, the mark is baked into the pixels like any other mark in a photograph, and the routes above no longer apply. What is left is cropping it away or covering it, both of which cost part of the picture and neither of which restores anything.
The second is a file you received rather than made. A background or a header picture can be deleted by anyone who opens the workbook, so the fix is four clicks in the copy you were sent. That is worth doing before looking for a service, and worth thinking about if the mark says the document is confidential or a draft.
What this site's tool does, stated plainly
The tool here opens PNG, JPEG, WebP, MP4, WebM and MOV. It does not open a spreadsheet or a presentation, and it holds one template — a single generator's badge, in the two layouts that generator has shipped. Nothing on this page is a promise that it will take a mark out of an Excel sheet or a PowerPoint deck, because it will not: those marks are document objects, and deleting a document object is a job for the program that holds it.
The short version
Excel has no watermark command. A background goes with Page Layout → Delete Background; a header picture goes when you delete the &[Picture] code in the header; a floating object goes with Go to Special → Objects → Delete. In PowerPoint the same mark usually lives on the slide master. All four are edits to the document, not repairs to a picture — which is the one thing every page promising to “remove a watermark from Excel” with an upload box gets wrong.

Source of the three routes described above: Page Layout → Delete Background for a sheet background; View → Page Layout followed by Insert → Header & Footer and the deletion of the &[Picture] code for a header image; and Home → Find & Select → Go to Special → Objects for a WordArt or shape mark, together with the caveat that this selects every object on the sheet. Also the source of the observations that a sheet background is not printed by default, that a header is set per sheet, and that a large header image can hide the code that placed it.
