copy(positionTypeString, relativeTo)	Copies a worksheet and places it at the specified position.
delete()	Deletes the worksheet from the workbook. Note that if the worksheet's visibility is set to "VeryHidden", the delete operation will fail with an `InvalidOperation` exception. You should first change its visibility to hidden or visible before deleting it.
findAll(text, criteria)	Finds all occurrences of the given string based on the criteria specified and returns them as a `RangeAreas` object, comprising one or more rectangular ranges.
findAllOrNullObject(text, criteria)	Finds all occurrences of the given string based on the criteria specified and returns them as a `RangeAreas` object, comprising one or more rectangular ranges.
getCell(row, column)	Gets the `Range` object containing the single cell based on row and column numbers. The cell can be outside the bounds of its parent range, so long as it stays within the worksheet grid.
getNext(visibleOnly)	Gets the worksheet that follows this one. If there are no worksheets following this one, this method will throw an error.
getNextOrNullObject(visibleOnly)	Gets the worksheet that follows this one. If there are no worksheets following this one, then this method returns an object with its `isNullObject` property set to `true`. For further information, see *OrNullObject methods and properties.
getPrevious(visibleOnly)	Gets the worksheet that precedes this one. If there are no previous worksheets, this method will throw an error.
getPreviousOrNullObject(visibleOnly)	Gets the worksheet that precedes this one. If there are no previous worksheets, then this method returns an object with its `isNullObject` property set to `true`. For further information, see *OrNullObject methods and properties.
getRange(address)	Gets the `Range` object, representing a single rectangular block of cells, specified by the address or name.
getRangeByIndexes(startRow, startColumn, rowCount, columnCount)	Gets the `Range` object beginning at a particular row index and column index, and spanning a certain number of rows and columns.
getRanges(address)	Gets the `RangeAreas` object, representing one or more blocks of rectangular ranges, specified by the address or name.
getUsedRange(valuesOnly)	The used range is the smallest range that encompasses any cells that have a value or formatting assigned to them. If the entire worksheet is blank, this function will return the top left cell (i.e. it will not throw an error).
getUsedRangeOrNullObject(valuesOnly)	The used range is the smallest range that encompasses any cells that have a value or formatting assigned to them. If the entire worksheet is blank, then this method returns an object with its `isNullObject` property set to `true`. For further information, see *OrNullObject methods and properties.
load(options)	Queues up a command to load the specified properties of the object. You must call `context.sync()` before reading the properties.
load(propertyNames)	Queues up a command to load the specified properties of the object. You must call `context.sync()` before reading the properties.
load(propertyNamesAndPaths)	Queues up a command to load the specified properties of the object. You must call `context.sync()` before reading the properties.
replaceAll(text, replacement, criteria)	Finds and replaces the given string based on the criteria specified within the current worksheet.

set(properties)	Sets multiple properties on the object at the same time, based on an existing loaded object.
showOutlineLevels(rowLevels, columnLevels)	Shows row or column groups by their outline levels. Outlines groups and summarizes a list of data in the worksheet. The `rowLevels` and `columnLevels` parameters specify how many levels of the outline will be displayed. The acceptable argument range is between 0 and 8. A value of 0 does not change the current display. A value greater than the current number of levels displays all the levels.
toJSON()	Overrides the JavaScript `toJSON()` method in order to provide more useful output when an API object is passed to `JSON.stringify()`. (`JSON.stringify`, in turn, calls the `toJSON` method of the object that is passed to it.) Whereas the original `Excel.Worksheet` object is an API object, the `toJSON` method returns a plain JavaScript object (typed as `Excel.Interfaces.WorksheetData`) that contains shallow copies of any loaded child properties from the original object.

Events

onActivated	Occurs when the worksheet is activated.
onCalculated	Occurs when the worksheet is calculated.
onChanged	Occurs when data changes in a specific worksheet.

getUsedRange(valuesOnly)

The used range is the smallest range that encompasses any cells that have a value or formatting assigned to them. If the entire worksheet is blank, this function will return the top left cell (i.e. it will not throw an error).

getUsedRange(valuesOnly?: boolean): Excel.Range;

Parameters

valuesOnly: boolean

Optional. If true, considers only cells with values as used cells (ignoring formatting). [Api set: ExcelApi 1.2]

Returns

Excel.Range

Remarks

set(properties, options)

Sets multiple properties of an object at the same time. You can pass either a plain object with the appropriate properties, or another API object of the same type.

set(properties: Interfaces.WorksheetUpdateData, options?: OfficeExtension.UpdateOptions): void;

Parameters

properties: Excel.Interfaces.WorksheetUpdateData

A JavaScript object with properties that are structured isomorphically to the properties of the object on which the method is called.

options: OfficeExtension.UpdateOptions

Provides an option to suppress errors if the properties object tries to set any read-only properties.

Returns

void

Examples

// Set the color and name of the current worksheet.
await Excel.run(async (context) => {
  const activeSheet = context.workbook.worksheets.getActiveWorksheet();
  activeSheet.set({
    tabColor: "yellow",
    name: "MySheet"
  });

set(properties: Excel.Worksheet): void;

Parameters

properties: Excel.Worksheet

Returns

void

showOutlineLevels(rowLevels, columnLevels)

Shows row or column groups by their outline levels. Outlines groups and summarizes a list of data in the worksheet. The rowLevels and columnLevels parameters specify how many levels of the outline will be displayed. The acceptable argument range is between 0 and 8. A value of 0 does not change the current display. A value greater than the current number of levels displays all the levels.

showOutlineLevels(rowLevels: number, columnLevels: number): void;

Parameters

rowLevels: number

The number of row levels of an outline to display.

columnLevels: number

The number of column levels of an outline to display.

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/excel/42-range/outline.yaml

Excel.run(async (context) => {
    const sheet = context.workbook.worksheets.getActiveWorksheet();

    // This shows the top 3 outline levels; collapsing any additional sublevels.
    sheet.showOutlineLevels(3, 3);
    await context.sync();
});

toJSON()

Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Excel.Worksheet object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.WorksheetData) that contains shallow copies of any loaded child properties from the original object.

toJSON(): Excel.Interfaces.WorksheetData;

Returns

Excel.Interfaces.WorksheetData
