Similar to exporting text, however mandatory the use of ", " in the separation of elements. Open PathName For Input As #FileNumber 'Opens the file in read mode 'Or enter a path Ex: PathName = "C:\test\database.txt"įileNumber = FreeFile ' Assigns the first available file number (Ex: #1) It is a very common type of file, and since each line refers several times to multiple columns, it may require a treatment with loops and functions, such as BOF and EOF.įor ease of import, the Line Input instruction (which works line by line), rather than just Input (which works character by character).

Returns the size in bytes of the defined #filenumber. Returns True if it has finished reading the defined #filenumber.
Returns True if it is at the beginning of the defined #filenumber. Important when working with multiple files. Returns the next available number for the Open statement. VbCrLf is a non-visible character CrLf indicates a line break in the file.

Because this is a text file, each byte is one character. LOF returns the number of bytes of the file opened with Open. MsgBox LOF(1) 'Total number of characters in file # 1Īllcharacters = Input(LOF(1), #1) 'Collect all characters from file # 1Ĭlose #1 'Close the file (number #1 to be reused) Open PathName For Input As #1 'File will be associated with the #1 'Notice that PathName will be a path String E.g. To collect all the characters at once we can use the LOF function: Sub LOFimport() To import content from a text file into Excel we will use an example file called "database.txt" and the function Input: To carry out these actions, we will need the help of the functions Input and Output respectively.

The following code will access the file you selected with Application.GetOpenFilename() Sub OpenTeste() If none is in use, FreeFile() will return 1. Use the FreeFile statement to get the next available file number. Normally the numbering starts at #1 and follows successively #2. The focus of this tutorial will be only on: Input ( import) and Output ( export).Įach open file must contain a numbering, a number between 1 and 511 preceded by a hashtag #.
