Remarks

[ API set: ExcelApi 1.1 ]

Examples

// Get a Worksheet object by its name and activate it.
await Excel.run(async (context) => { 
    const wSheetName = 'Sheet1';
    const worksheet = context.workbook.worksheets.getItem(wSheetName);
    worksheet.activate();
    await context.sync(); 
});

Properties

autoFilter

Represents the AutoFilter object of the worksheet.

charts

Returns a collection of charts that are part of the worksheet.

comments

Returns a collection of all the Comments objects on the worksheet.

context

The request context associated with the object. This connects the add-in's process to the Office host application's process.

customProperties

Gets a collection of worksheet-level custom properties.

enableCalculation

Determines if Excel should recalculate the worksheet when necessary. True if Excel recalculates the worksheet when necessary. False if Excel doesn't recalculate the sheet.

freezePanes

Gets an object that can be used to manipulate frozen panes on the worksheet.

horizontalPageBreaks

Gets the horizontal page break collection for the worksheet. This collection only contains manual page breaks.

id

Returns a value that uniquely identifies the worksheet in a given workbook. The value of the identifier remains the same even when the worksheet is renamed or moved.

name

The display name of the worksheet. The name must be fewer than 32 characters.

names

Collection of names scoped to the current worksheet.

pageLayout

Gets the PageLayout object of the worksheet.

pivotTables

Collection of PivotTables that are part of the worksheet.

position

The zero-based position of the worksheet within the workbook.

tabColor

The tab color of the worksheet. When retrieving the tab color, if the worksheet is invisible, the value will be null. If the worksheet is visible but the tab color is set to auto, an empty string will be returned. Otherwise, the property will be set to a color, in the form #RRGGBB (e.g., "FFA500"). When setting the color, use an empty-string to set an "auto" color, or a real color otherwise.

tables

Collection of tables that are part of the worksheet.

verticalPageBreaks

Gets the vertical page break collection for the worksheet. This collection only contains manual page breaks.

visibility

Methods

activate()

Activate the worksheet in the Excel UI.

calculate(markAllDirty)

Calculates all cells on a worksheet.

copy(positionType, relativeTo)

Copies a worksheet and places it at the specified position.

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, 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)

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.

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

Remarks

[ API set: ExcelApi 1.1 ]

Examples

await Excel.run(async (context) => { 
    const wSheetName = 'Sheet1';
    const worksheet = context.workbook.worksheets.getItem(wSheetName);
    const usedRange = worksheet.getUsedRange();
    usedRange.load('address');
    await context.sync();
    
    console.log(usedRange.address);
});

getUsedRangeOrNullObject(valuesOnly)

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

Parameters

valuesOnly

boolean

Optional. Considers only cells with values as used cells.

Returns

The number of replacements performed.

Remarks

[ API set: ExcelApi 1.9 ]

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"
  });

  await context.sync();
});

set(properties)

Sets multiple properties on the object at the same time, based on an existing loaded object.

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.

Returns

void

Remarks

[ API set: ExcelApi 1.10 ]

Examples

// 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
