Sheet protection helps you to prevent the users from modifying the data in the spreadsheet.

Protect Sheet

Protect sheet feature helps you to prevent the unknown users from accidentally changing, editing, moving, or deleting data in a spreadsheet.
You can use the isProtected property to enable or disable the Protecting functionality.

The default value for isProtected property is false.

By default in protected sheet, selecting, formatting, inserting, deleting functionalities are disabled. To enable some of the above said functionalities the protectSettings options are used in a protected spreadsheet.

The available protectSettings options in spreadsheet are,

Options	Uses
`Select Cells`	Used to perform Cell Selection.
`Format Cells`	Used to perform Cell formatting.
`Format Rows`	Used to perform Row formatting.
`Format Columns`	Used to perform Column formatting.
`Insert Link`	Used to perform Hyperlink Insertions.

The default value for all protectSettings options are false.

By default, the Protect Sheet module is injected internally into the Spreadsheet to perform sheet protection function.

User Interface:

In the active Spreadsheet, the sheet protection can be done by any of the following ways:

Select the Protect Sheet item in the Ribbon toolbar under the Data Tab, and then select your desired options.
Right-click the sheet tab, select the Protect Sheet item in the context menu, and then select your desired options.
Use the protectSheet() method programmatically.

The following example shows Protect Sheet functionality in the Spreadsheet control.

app.vue
<template>
  <ejs-spreadsheet ref="spreadsheet" :created="created">
                <e-sheets>
                  <e-sheet name="Budget" :isProtected="true" :protectSettings="{ selectCells: true }">
                    <e-ranges>
                      <e-range :dataSource="dataSource1"></e-range>
                    </e-ranges>
