Trying to save an .xlsx file attached to an email into a local directory

Hello Guys,

I am trying to fetch an email attachment which is a .xlsx file.
I moved the arraybuffer of the attachment content to msg.payload and used file node to try to save it as test.xlsx.
But the saved .xlsx file is currupt.
And the strage part is it did work as i intended once so i am totaly lost what exactly is the problem.
Ive mentioned the code for the flow below.

[{"id":"227f4b0e.7a7ac4","type":"inject","z":"ed20e334.d0265","name":"","topic":"","payload":"","payloadType":"date","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":100,"y":917,"wires":[["a512ec0f.4c98a"]]},{"id":"a512ec0f.4c98a","type":"e-mail in","z":"ed20e334.d0265","name":"Office email","protocol":"IMAP","server":"outlook.office365.com","useSSL":true,"port":"993","box":"IOT","disposition":"Read","criteria":"FLAGGED","repeat":"300","fetch":"trigger","inputs":1,"x":110,"y":997,"wires":[["f4b39742.fb9b58"]]},{"id":"f0d976ef.784b68","type":"debug","z":"ed20e334.d0265","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","x":750,"y":997,"wires":[]},{"id":"f4b39742.fb9b58","type":"filter","z":"ed20e334.d0265","name":"mfg cost","property":"topic","propertyType":"msg","asArray":false,"itemProperty":"","itemPropertyType":"item","rules":[{"t":"cont","v":"Mfg cost for the month of ","vt":"str","output":1}],"checkall":"true","outputs":1,"x":260,"y":997,"wires":[["9eb64d36.1aa6d"]]},{"id":"9eb64d36.1aa6d","type":"change","z":"ed20e334.d0265","name":"move to payload","rules":[{"t":"move","p":"attachments[0].content","pt":"msg","to":"payload","tot":"msg"}],"action":"","property":"","from":"","to":"","reg":false,"x":430,"y":997,"wires":[["1bbd5c41.6018d4"]]},{"id":"1bbd5c41.6018d4","type":"file","z":"ed20e334.d0265","name":"test","filename":"E:\\greenshot\\email attachment test\\test.xlsx","appendNewline":true,"createDir":false,"overwriteFile":"true","encoding":"utf8","x":610,"y":997,"wires":[["f0d976ef.784b68"]]}]

Well you probably shouldn't add a carriage return to the end of the file as that may corrupt it
image
Also utf8 format "may" be ok - but I would probably try binary as it won't try and be too clever with extended characters.

Hi, thanks for the reply. I just chnage encoding to default and it worked.
