Hello, I'm new to Node-RED. Having some trouble with sending data to CSV. I need two separate columns with different names and different data below for example but I'm getting everything in one line. Please tell me how to solve this. Thank you [{"id":"2f90ce8fb2a257e8","type":"tab","label":"Flow 2…

You are adding a \n in csv node, and also appending one in file write node. Either add one in csv node, or file write node, but not both nodes.

We cannot use that code, please replace by pasting the code into a preformatted text blog.

Looking at your function code you are sending a single object into the csv node. If you require multiple lines then you would need to send an array of objects, an object for each line. e.g. [ { "Time": 10, "Sensor": 50 }, { "Time": 15, "Sensor": 20 } ]

Yes. I see a single object on a debug node - (time with value and sensor with value). I want to get - (1 column - Time with value below), (2 column - Sensor with value below).

That is what you get. it is the followed by a carriage return \r and a new line \n. This is a text csv format. As image shows [chrome_screenshot_28 Mar 2024 17_40_10 GMT] Attach the file that is created after you click inject several times, as i see no errors.

As said all working correct [Screenshot_20240328-174235] Unless you want one header row and only one value row, if so set csv node to always send header and file write node to overwrite and not append.

Hmm, maybe is something wrong with my Excel or something else, have no idea. This is what I want to achieve - [test]

When I open test,csv in my spreadsheet I get [Screenshot_20240328-175515] Must be an issue on your device/spreadsheet program if it is not opening like above.

So I achieved what I wanted just not for myself yet :smiley: I'll try to check my software settings later, whats wrong with my MS Excel.

Not a windows user, so can not help you there, sorry.
