#### Workbook File Properties
|
||
|
|
|
||
|
|
The various file formats use different internal names for file properties. The
|
||
|
|
workbook `Props` object normalizes the names:
|
||
|
|
|
||
|
|
<details>
|
||
|
|
<summary><b>File Properties</b> (click to show)</summary>
|
||
|
|
|
||
|
|
| JS Name | Excel Description |
|
||
|
|
|:--------------|:-------------------------------|
|
||
|
|
| `Title` | Summary tab "Title" |
|
||
|
|
| `Subject` | Summary tab "Subject" |
|
||
|
|
| `Author` | Summary tab "Author" |
|
||
|
|
| `Manager` | Summary tab "Manager" |
|
||
|
|
| `Company` | Summary tab "Company" |
|
||
|
|
| `Category` | Summary tab "Category" |
|
||
|
|
| `Keywords` | Summary tab "Keywords" |
|
||
|
|
| `Comments` | Summary tab "Comments" |
|
||
|
|
| `LastAuthor` | Statistics tab "Last saved by" |
|
||
|
|
| `CreatedDate` | Statistics tab "Created" |
|
||
|
|
|
||
|
|
</details>
|
||
|
|
|
||
|
|
For example, to set the workbook title property:
|
||
|
|
|
||
|
|
```js
|
||
|
|
if(!wb.Props) wb.Props = {};
|
||
|
|
wb.Props.Title = "Insert Title Here";
|
||
|
|
```
|
||
|
|
|
||
|
|
Custom properties are added in the workbook `Custprops` object:
|
||
|
|
|
||
|
|
```js
|
||
|
|
if(!wb.Custprops) wb.Custprops = {};
|
||
|
|
wb.Custprops["Custom Property"] = "Custom Value";
|
||
|
|
```
|
||
|
|
|
||
|
|
Writers will process the `Props` key of the options object:
|
||
|
|
|
||
|
|
```js
|
||
|
|
/* force the Author to be "SheetJS" */
|
||
|
|
XLSX.write(wb, {Props:{Author:"SheetJS"}});
|
||
|
|
```
|
||
|
