Install:

Officeprops relies on JSZip which has to be included alongside this package if not using node.

Node:
``
npm install officeprops
`
Or include via cdn:
`


`

Usage:

The package adds a global "OFFICEPROPS" variable.

All functions take a File or Blob as parameter, or a Buffer in Node.


##### Get metadata:
`javascript
OFFICEPROPS.getData(file).then(function(metadata){
console.log(metadata.editable);
console.log(metadata.readOnly);
})
`

##### Metadata Format:
Open office property names are translated to MS Office names. e.g. "editing-duration" becomes "totalTime".
Returns the actual value, as well as a translated one for each property.
`javascript
metadata = {
editable: {
totalTime: {
value: "PT3M43S", //actual value
tvalue: "3 minutes", //translated value
xmlPath: "office:meta/meta:editing-duration"
},
creator: {
value: "Torkel Velure",
tvalue: "Torkel Velure",
xmlPath: "office:meta/meta:initial-creator"
}
//...see OFFICEPROPS.properties for full list of properties
},
readOnly: {
slideTitles: ["Slide1, slide2, slide3"],
titles: ["title1", "title2"],
worksheets: ["sheet1"]
}
}
`

##### Edit metadata:

`javascript
OFFICEPROPS.getData(file).then(function(metadata){
metadata.editable.creator.value = "New author";
OFFICEPROPS.editData(file,metadata).then(function(officeFile){
console.log(officeFile) // blob/nodestream containing edited file.
})
})
`


##### Remove metadata:
`javascript
OFFICEPROPS.removeData(file).then(function(officeFile){
console.log(officeFile) // blob/nodestream with metadata removed.
})
``
