Windows, Application

Microsoft Excel. Calculation threads and Power Query fit keep EXCEL.EXE busy afta di grid look like e dey idle.

## Wetin you need know

Dis na Excel. Recalc and Power Query na why workbook wey look quiet still dey chop CPU core.

EXCEL.EXE na Microsoft Excel. Manual calc, volatile functions, and Power Query refreshes na things wey dey make Excel specifically use CPU. Word no get calculation engine like dis.

- **E safe?**: Check the running file path, signature, and publisher. Name alone no fit confirm say e safe.

  **High CPU on top "simple" sheet?**: Formula wey no dey stable or Power Query fit cause am. Compare di actual workbook workload.

  **Same thing as WINWORD?**: No. Different Office app

Feex tok say

If Excel dey at 80 percent and di sheet look idle, I go check status bar for Calculating and Power Query. I no go disable SysMain for dat one.

## Wetin be EXCEL.EXE?

EXCEL.EXE na Microsoft Excel. Click-to-Run dey put am near WINWORD.EXE. Di image name match di product, unlike Word.

## Wetin e dey do?

E dey calculate workbooks, dey run VBA, and e fit keep Power Query or Power Pivot work inside di process. Multiple EXCEL.EXE rows fit be separate instances if na so you launch dem.

## Wetin make am dey run?

Workbook dey open, DDE launch from another app start Excel, or preview handler open sheet.

## Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

`Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'EXCEL.EXE' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List`

No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local. (pcm)

Use the [file-identity guide](https://feex.it/wiki/l/pcm/software/system/verify-executable-path-signature/) to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

## E dey safe?

Check dis running file

Office16\EXCEL.EXE wey Microsoft sign na Excel. excel.exe inside macro-phishing zip na di attachment, no be Office.

Compare the recorded location with the actual file. A familiar folder alone no fit establish identity. (pcm)

`C:\Program Files\Microsoft Office\root\Office16\EXCEL.EXE`

- Office Click-to-Run path
- Calculation threads still be dis image
- Add-ins and COM fit hang am

## I fit end am?

You go lose workbooks wey you never save

To end EXCEL.EXE dey drop unsaved books. Recovery fit help. Cancel Power Query refresh before you kill di process if di UI still dey respond.

## I fit comot am?

Uninstall Office

No delete EXCEL.EXE. Repair or uninstall Microsoft 365 Apps.

## E suppose start with Windows?

Excel no suppose start at logon unless file or shortcut tok say make e start.

## Measure resource use

| CPU and memory   | Compare several observations for the same PID and workload. This entry get no independently measured universal baseline. (pcm)               |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------------- |
| Disk and network | Attribute activity to the actual process and current task; a filename alone no fit establish expected destinations or transfer volume. (pcm) |

## File information

| Executable name            | EXCEL.EXE                                                                          |
| -------------------------- | ---------------------------------------------------------------------------------- |
| Recorded installation path | C:\Program Files\Microsoft Office\root\Office16\EXCEL.EXE                          |
| Publisher                  | Microsoft Corporation                                                              |
| Signature check            | Inspect the actual file; this entry no dey certify its certificate identity. (pcm) |

## Common wahala dem

### Calculating inside status bar

Na Excel dey do math so. SysMain and Defender na different rows. Pause recalc or move volatile formulas.

### Two Excels

DDE versus second instance na Office launch setting, no be duplicate install.

## How to troubleshoot

Diagnose before you change anything wey fit scatter things.

### excel /safe for add-ins

Same idea like Word, different exe. If Safe Mode quiet, disable COM add-ins.

### Check 32-bit versus 64-bit Office

2 GB sheet inside 32-bit Excel na product-bitness wahala, no be Windows process wahala.
