Protect an Excel worksheet

By Jetformat

Select the worksheet to protect. This differs from protecting workbook structure and should not be described as encrypting the XLSX file.

Steps

Start with a local XLSX. Replace the sample paths and identifiers with your own.
Run the command below. Save to a new output path so the source remains available for comparison.
Check the result as described below before using it in another job.

jetformat excel protect-sheet finance.xlsx --sheet Summary --password secret -o finance-updated.xlsx

Options for this task

Option	Meaning
`--output`	Output XLSX path (required)
`--password`	Optional password
`--sheet`	Worksheet name (required)

Check the result

Open the saved sheet and check editing restrictions in the viewer that recipients will use.

Notes and limits

Writing an Office document uses one credit per command. See the billing guide for the current rules.

The examples keep the original file. Add --force only when you intend to overwrite an existing output. Run jetformat excel protect-sheet --help to compare options with your installed version.

See the excel command reference for the surrounding workflow.
