How to create and write to a txt file using VBA

I have a file which is manually added or modified based on the inputs. Since most of the contents are repetitive in that file, only the hex values are changing, I want to make it a tool generated file.

I want to write the c codes which are going to be printed in that .txt file.

What is the command to create a .txt file using VBA, and how do I write to it

Use FSO to create the file and write to it.

Dim fso as Object
Set fso = CreateObject("Scripting.FileSystemObject")
Dim oFile as Object
Set oFile = FSO.CreateTextFile(strPath)
oFile.WriteLine "test" 
oFile.Close
Set fso = Nothing
Set oFile = Nothing

Open ThisWorkbook.Path & "\template.txt" For Output As #1
Print #1, strContent
Close #1

To elaborate on Ben's answer:

If you add a reference to Microsoft Scripting Runtime and correctly type the variable fso you can take advantage of autocompletion (Intellisense) and discover the other great features of FileSystemObject.

Here is a complete example module:

Option Explicit

' Go to Tools -> References... and check "Microsoft Scripting Runtime" to be able to use
' the FileSystemObject which has many useful features for handling files and folders
Public Sub SaveTextToFile()
 
    Dim filePath As String
    filePath = "C:\temp\MyTestFile.txt"
 
    ' The advantage of correctly typing fso as FileSystemObject is to make autocompletion
    ' (Intellisense) work, which helps you avoid typos and lets you discover other useful
    ' methods of the FileSystemObject
    Dim fso As FileSystemObject
    Set fso = New FileSystemObject
    Dim fileStream As TextStream
    
    ' Here the actual file is created and opened for write access
    Set fileStream = fso.CreateTextFile(filePath)
    
    ' Write something to the file
    fileStream.WriteLine "something"
    
    ' Close it, so it is not locked anymore
    fileStream.Close
    
    ' Here is another great method of the FileSystemObject that checks if a file exists
    If fso.FileExists(filePath) Then
        MsgBox "Yay! The file was created! :D"
    End If
    
    ' Explicitly setting objects to Nothing should not be necessary in most cases, but if
    ' you're writing macros for Microsoft Access, you may want to uncomment the following
    ' two lines (see https://stackoverflow.com/a/517202/2822719 for details):
    'Set fileStream = Nothing
    'Set fso = Nothing
 
End Sub

an easy way with out much redundancy.

    Dim fso As Object
    Set fso = CreateObject("Scripting.FileSystemObject")
    
    Dim Fileout As Object
    Set Fileout = fso.CreateTextFile("C:\your_path\vba.txt", True, True)
    Fileout.Write "your string goes here"
    Fileout.Close

Dim SaveVar As Object

Sub Main()

    Console.WriteLine("Enter Text")

    Console.WriteLine("")

    SaveVar = Console.ReadLine

    My.Computer.FileSystem.WriteAllText("N:\A-Level Computing\2017!\PPE\SaveFile\SaveData.txt", "Text: " & SaveVar & ", ", True)

    Console.WriteLine("")

    Console.WriteLine("File Saved")

    Console.WriteLine("")

    Console.WriteLine(My.Computer.FileSystem.ReadAllText("N:\A-Level Computing\2017!\PPE\SaveFile\SaveData.txt"))
    Console.ReadLine()

End Sub()
