A .CEL file can refer to several unrelated formats, so its explanation depends entirely on the software or field that produced it; in biotech/genomics it most often represents an Affymetrix/Thermo Fisher GeneChip microarray output that stores raw probe-intensity values from a scanned chip, where each tiny probe spot on the array is measured for brightness after hybridization, and the CEL file records those intensity readings—often indexed by X/Y grid location—along with scan metadata, forming "raw" data that still needs downstream steps like background correction, normalization, and probe summarization using tools such as R/Bioconductor’s oligo, plus companion files like .CDF and .CHP.

In graphics pipelines, "cel" is rooted in traditional cel layers, and a CEL file typically stores a single raster frame or semi-transparent layer meant to be stacked over others, usually part of a numbered sequence like `walk_002.cel` with palette files nearby; because many tools invented their own CEL variants, some files load fine in common viewers while others need the specific editor or palette, and some games further overload `.CEL` for sprites or proprietary assets, so the extension alone doesn’t define it, and the quickest way to classify it is to check its origin, neighboring files, naming/size clues, and a small peek in a text/hex viewer.

In 2D animation, a "cel" is based on the physical cels once used frame by frame where each sheet carried a single drawing over a fixed background, and digital animation maintains that layered system; a CEL file thus represents a raster layer—like a character part, lip-sync element, or visual effect—using transparency so only the artwork appears when stacked with other layers.

Because ".CEL" has shifted across various tools, a CEL file may be palette-based, tool-specific, or dependent on an external palette, which is why they often appear in art-production folders like `frames` or `cels` in sequences such as `idle_001.cel`; opening them can be simple or may need the original application, and the CEL itself is just one raster frame/layer that gets composited with others during animation.

To figure out what type of .CEL file you’re dealing with, it helps to treat the extension as secondary and focus on origin: genomics sources and keywords like GEO or microarray suggest a raw microarray CEL, while animation or game directories point to image or asset cels; next, check the surrounding files—microarray CELs often live near .CDF or .CHP, whereas animation/game CELs show up in numbered sequences with palettes—and then inspect file size and open it safely in a text or hex viewer to see whether you get readable probe/scan info or mostly binary asset data.

".CEL isn’t a single universal standard" highlights that the letters don’t guarantee a specific file type, because different companies and industries have reused ".cel" for unrelated purposes, treating it as a simple filename suffix rather than a format with a shared specification; that’s why an Affymetrix CEL can store probe-intensity data, an animation CEL can be a raster frame with transparency, and a game CEL can be a proprietary sprite/resource file—same extension but entirely different "languages" inside, making context or header inspection necessary to know which tool can open it.
