Error reading date from file xlsx

Hello everyone? Are you all doing well?

I have a small problem with N8N. Can someone help me?

Here’s the issue: I have stored my Excel file in a database. Then, I make an API Request to retrieve the row containing the file. After that, I use another API Request to fetch the file, and I use the Spreadsheet module to read the data from the file.

My problem is that I can’t get the date formats from the file. I have enabled “Read as String,” but it gives me an error. My date formats are in numbers that only Excel can translate into dates.

Hi @Micka_Rakotomalala, I am very sorry to hear you’re having trouble :frowning:

The date format you are seeing (values such as 44562 or 44047) are no actual errors, but instead are how Excel stores dates. n8n does not have built-in functionality to automatically convert these, but you can use a Set node with a bit of Excel specific logic to process these. Check out Date serial number to normal date - #4 by MutedJam for details and please do let me know if you are still running into any trouble with this :slight_smile:

Hello @MutedJam, thank you very much for your reply.

I used a code node to solve the date problem. I couldn’t answer because I was away for a while.
That’s solved, thank you very much.

I’ll test in the set node as you said, it’s faster and more efficient.
