**Simple Defined Names**: XLSX/M, XLSB, BIFF8 XLS, XLML, ODS, SYLK
|

**Unicode Defined Names**: XLSX/M, XLSB, BIFF8 XLS, XLML, ODS

`wb.Workbook.Names` is an array of defined name objects which have the keys:
|
||||
|
||||
| Key | Description |
|
||||
|:----------|:-----------------------------------------------------------------|
|
||||
| `Sheet` | Name scope. Sheet Index (0 = first sheet) or `null` (Workbook) |
|
||||
| `Name` | Case-sensitive name. Standard rules apply ** |
|
||||
| `Ref` | A1-Style Reference (`"Sheet1!$A$1:$D$20"`) |
|
||||
| `Comment` | Comment (only applicable for XLS/XLSX/XLSB) |
|
||||
|
||||
Excel allows two sheet-scoped defined names to share the same name. However, a
|
||||
sheet-scoped name cannot collide with a workbook-scope name. Workbook writers
|
||||
may not enforce this constraint.
|
||||
|
||||
The following snippet creates a worksheet-level defined name `"Global"` and a
|
||||
local defined name `"Local"` with distinct values for first and second sheets:
|
||||
|
||||
```js
|
||||
/* ensure the workbook structure exists */
|
||||
if(!wb.Workbook) wb.Workbook = {};
|
||||
if(!wb.Workbook.Names) wb.Workbook.Names = [];
|
||||
|
||||
/* "Global" workbook-level -> Sheet1 A1:A2 */
|
||||
wb.Workbook.Names.push({ Name: "Global", Ref: "Sheet1!$A$1:$A$2" });
|
||||
|
||||
/* "Local" scoped to the first worksheet -> Sheet1 B1:B2 */
|
||||
wb.Workbook.Names.push({ Name: "Local", Ref: "Sheet1!$B$1:$B$2", Sheet: 0 });
|
||||
|
||||

# Defined Names
|
||||
|
||||
<details>
|
||||
<summary><b>File Format Support</b> (click to show)</summary>
|
||||
|
||||
Defined names have evolved over the decades, with new features added over time:
|
||||
|
||||
- "English" refers to defined names with English letters and numbers (ASCII)
|
||||
- "Unicode" refers to defined names that non-English characters.
|
||||
- "Comment" refers to comments that can be attached to defined names.
|
||||
|
||||
| Formats | English | Unicode | Comment |
|
||||
|:------------------|:-------:|:-------:|:-------:|
|
||||
| XLSX / XLSM | ✔ | ✔ | ✔ |
|
||||
| XLSB | ✔ | ✔ | ✔ |
|
||||
| XLS | ✔ | ✔ | ✔ |
|
||||
| XLML | ✔ | ✔ | |
|
||||
| SYLK | ✔ | * | |
|
||||
| ODS / FODS / UOS | ✔ | ✔ | |
|
||||
|
||||
Asterisks (*) mark features that are not supported by the file formats. There is
|
||||
no way to specify a Unicode defined name in the SYLK format.
|
||||
|
||||
</details>
|
||||
|
||||
`wb.Workbook.Names` is an array of defined name objects which have the keys:
|
||||
|
||||
| Key | Name in app | Description |
|
||||
|:----------|:------------|:---------------------------------------------------|
|
||||
| `Sheet` | "Scope" | Sheet Index (0 = first sheet) or `null` (Workbook) |
|
||||
| `Name` | "Name" | Case-sensitive name. Standard rules apply |
|
||||
| `Ref` | "Refers To" | A1-Style Reference (`"Sheet1!$A$1:$D$20"`) |
|
||||
| `Comment` | "Comment" | Comment (for supported file formats) |
|
||||
|
||||
Parsers do not always create the `Names` structure. Parsing and writing code
|
||||
should test for the existence of the defined names array before use:
|
||||
|
||||
```js
|
||||
/* ensure the workbook structure exists */
|
||||
if(!wb.Workbook) wb.Workbook = {};
|
||||
if(!wb.Workbook.Names) wb.Workbook.Names = [];
|
||||
|
||||
/* add a new defined name */
|
||||
wb.Workbook.Names.push({ Name: "MyData", Ref: "Sheet1!$A$1:$A$2" });
|
||||
```
|
||||
|
||||
## Ranges
|
||||
|
||||
Defined name references in formulae are internally shifted to the cell address.
|
||||
For example, given the defined name
|
||||
|
||||
```js
|
||||
{ Name: "MyData", Ref: "Sheet1!A1:A2" } // no $ means relative reference
|
||||
```
|
||||
|
||||
If `D4` is set to `=SUM(MyData)`:
|
||||
|
||||
```js
|
||||
ws["D4"].f = "SUM(MyData)";
|
||||
```
|
||||
|
||||
Spreadsheet software will translate the defined name range down to the cell.
|
||||
Excel will try to calculate `SUM(D4:D5)` and assign to cell `D4`. This will
|
||||
elicit a circular reference error.
|
||||
|
||||
The recommended approach is to fix the rows and columns of the reference:
|
||||
|
||||
```js
|
||||
{ Name: "MyData", Ref: "Sheet1!$A$1:$A$2" } // absolute reference
|
||||
```
|
||||
|
||||
## Scoped Defined Names
|
||||
|
||||
Excel allows two sheet-scoped defined names to share the same name. However, a
|
||||
sheet-scoped name cannot collide with a workbook-scope name. Workbook writers
|
||||
may not enforce this constraint.
|
||||
|
||||
The following snippet creates a worksheet-level defined name `"Global"` and a
|
||||
local defined name `"Local"` with distinct values for first and second sheets:
|
||||
|
||||
```js
|
||||
/* "Global" workbook-level -> Sheet1 A1:A2 */
|
||||
wb.Workbook.Names.push({ Name: "Global", Ref: "Sheet1!$A$1:$A$2" });
|
||||
|
||||
/* "Local" scoped to the first worksheet -> Sheet1 B1:B2 */
|
||||
wb.Workbook.Names.push({ Name: "Local", Ref: "Sheet1!$B$1:$B$2", Sheet: 0 });
|
||||
|
||||
/* "Local" scoped to the second worksheet -> Sheet1 C1:C2 */
|
||||
wb.Workbook.Names.push({ Name: "Local", Ref: "Sheet1!$C$1:$C$2", Sheet: 1 });
|
||||
```
|
||||
|
||||
## Live Demo
|
||||
|
||||
The following example creates 3 defined names:
|
||||
|
||||
- "Global" is a workbook-level name that references `Sheet1!$A$1:$A$2`
|
||||
- "Local" in the first worksheet references `Sheet1!$B$1:$B$2`
|
||||
- "Local" in the second worksheet references `Sheet1!$C$1:$C$2`
|
||||
|
||||
Both worksheets include formulae referencing "Local" and "Global". Since the
|
||||
referenced ranges are different, the expressions using "Local" will differ.
|
||||
|
||||
```jsx live
|
||||
/* The live editor requires this function wrapper */
|
||||
function DefinedNameExport() { return ( <button onClick={() => {
|
||||
/* Create empty workbook */
|
||||
var wb = XLSX.utils.book_new();
|
||||
|
||||
/* Create worksheet Sheet1 */
|
||||
var ws1 = XLSX.utils.aoa_to_sheet([[1,2,3],[4,5,6],["Global",0],["Local",0]]);
|
||||
XLSX.utils.book_append_sheet(wb, ws1, "Sheet1");
|
||||
|
||||
/* Create worksheet Sheet2 */
|
||||
var ws2 = XLSX.utils.aoa_to_sheet([["Global",0],["Local",0]]);
|
||||
XLSX.utils.book_append_sheet(wb, ws2, "Sheet2");
|
||||
|

/* Create defined names */
|
||||
if(!wb.Workbook) wb.Workbook = {};
|

if(!wb.Workbook.Names) wb.Workbook.Names = [];

/* "Global" workbook-level -> Sheet1 A1:A2 */

/* "Local" scoped to the first worksheet -> Sheet1 B1:B2 */
|
||||
wb.Workbook.Names.push({ Name: "Local", Sheet: 0, Ref: "Sheet1!$B$1:$B$2" });
|
||||
/* "Local" scoped to the second worksheet -> Sheet1 C1:C2 */
