### To Upload to View.

I would:

1. I would write the uploaded byte into tempFilePath:

```python
	#creates a temporary file (with given extension) on host
	tempFilePath = system.file.getTempFile(fileExt)
	#write file byte to temporary file
	system.file.writeFile(tempFilePath, fileByte)

```

1. How do I extract the file bite into json and write to custom property?

### To Download, I would:

1. Convert to bytes and download:

```python
	system.perspective.download(filename, excelBytes)

```

1. How do I convert jsonText to file?

Upload, assuming you're in the context of the File Upload component (because that's the only way to load a file into Perspective):

> **[Perspective - File Upload Scripting | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.3/appendix/components/perspective-components/perspective-input-palette/perspective-file-upload/perspective-file-upload-scripting)**

```python
jsonString = event.file.getString()
json = system.util.jsonDecode(jsonString)

self.custom.myCustomProperty = json

```

Downloading is the inverse operation:

```python
jsonString = system.util.jsonEncode(self.custom.myCustomProperty)
system.perspective.download(filename, jsonString, contentType="application/json")

```
