The Internet to find EXCEL file with multiple methods, ideas:
A, Linux or window + cmder, directly from the command line cat merge EXCEL file, however, you need to install a secondary thing to deal directly (and perhaps can not, however, convert a file format conversion tool is feasible to convert the file into EXCEL txt file, re-operation, good operation, converted to EXCEL format); there is a perl or Python has its own built-in EXCEL processing package, can be like handling arrays, direct purpose of processing EXCEL file
Two, EXCEL VBA programming comes with the merger, however, a lot of online search, the format is very similar to the VBA script, can not achieve perfect merge functions are more or less associated with incomplete phenomenon, then encountered the following this version can be well implemented correctly merge, in this script inside each of the functions to the detailed notes about, if not the right place, welcome message, grateful ~

Note: The first line is the line had to be merged header, leaving only a first line and a merged document, there is no row header to be wrong, missing data; cell A1 of each file can not be merged is empty cell, otherwise the entire file will not do the merger;
Example:
1 files are:
2 files are:
1, 2 are combined to file, an empty file is a new 3; to put a directory folder;
3 Open the file, open the VBA, paste the script save, save the file 3 file format to enable macros;
Run the macro;

（1）Resize
Resize Range object using the specified size of the area attribute adjustment, and returns the size range of cells adjusted, as shown in the code below.
The Resize Sub ()
. Sheet4.Range ( "A1") the Resize (3, 3) .Select 'means that the cells in the worksheet A1 4 is expanded to the size of the area of 3 rows and 3 columns, the result is A1: C3 region
End Sub
code analysis:
Resize process uses Range Resize object properties of the selected cell A1 expanded region after three rows and three columns.
Resize attribute syntax is as follows:
expression.Resize (RowSize, the ColumnSize)
Parameters expression is required, return the object to adjust the size of the Range
parameter RowSize is optional, the number of rows in the new region. If omitted, the number of rows in the region remains unchanged.
ColumnSize parameter is optional, the number of columns in the new region. If you omitted. The number of columns in the region remains unchanged.

(2) you
Custom function determines whether the configuration file exists in function This is a VBA the Dir ()
Function FileExists(fname) As Boolean ' Returns TRUE if the file exists Dim x As String x = Dir(fname) If x <> "" Then FileExists = True _ Else FileExists = False End Function
////////////////////////////////////////////////// ////////////////////////////////////////////////// ////////////////////////////////// Dir function
Returns a String , to represent a file name, directory name or folder name, which must match a specified pattern or file attribute, or a disk label.
grammar
Dir[(pathname[, attributes])]
Dir grammar function has the following parts:
Part Description pathname optional parameters. It is used to specify the filename string expression, may contain directories or folders, and drives. If you do not find the pathname , it will return a zero-length string ( ""). attributes Optional. Numeric constant or expression that is used to specify the total file attributes. If omitted, it will return a match pathname file but does not contain the property.
Settings
attributes set the parameters may be:
Constants described vbNormal 0 (default) does not attribute file. vbReadOnly . 1 specifies no read-only file attribute vbHidden 2 specifies no hidden file attribute vbSystem . 4 no attribute specified in the Macintosh file system is not available. vbVolume 8 specify the volume label file; if the other attributes specified, is ignored vbVolume the Macintosh is not available. vbDirectory 16 properties file and specify no path and folder. vbAlias 64-specified file name is an alias, available only on the Macintosh.
Note that these constants are designated by the VBA, anywhere in the program code, the real value may be replaced with these constants.
Explanation
In Microsoft Windows, Dir supports multiple character ( *) and single character ( ?) Wildcards to specify multiple files.
On the Macintosh, these characters as a legitimate file name characters and not as a wildcard to specify multiple files
Since the Macintosh does not support wildcards, file types specified file group. You can use MacID function to specify file type instead of the file name. For example, the following statement returns the name of the first file in the current folder TEXT:
Dir("SomePath", MacID("TEXT"))
All files for the selected folder, specify an empty string:
Dir("")
In Microsoft Windows, if the Dir using the function MacID function, an error occurs.
No greater than 256 attribute values are considered MacID value of the function.
In the first call Dir a function, you must specify pathname , otherwise it will generate an error. If you also specify the file attribute, then it must include the pathname .
Dir will return a match pathname of a file name. If you want to get other matching pathname of the file name, and once again call Dir , and do not use parameters. If the file is not in line with the conditions, the Dir returns a zero-length string ( ""). Once the return value is zero-length string, and to be called again Dir time, you must specify pathname , otherwise it will generate an error. Do not have access to all match the current pathname of the file name, you can change to a new pathname on. However, it can not be called recursively Dir function. To vbDirectory property to call the Dir can not continually return subdirectories.
Tip Since the file name in a special order and will not be returned, so it can be in an array, and then sort the file names are stored on the array.

（3）Set
VBA is SET in a customized object properties and methods
Excel version Reference: 2010
1, grammar
Set objectvar = {[New]
objectexpression | Nothing}
Set statement syntax has the following parts:
description
objectvar
Required. Name of the variable or property, follows standard variable naming conventions.
New
Optional. New typically used in the statement, so that you can implicitly created object. If the New and
Used with Set, a new instance of the class is created. in case
objectvar contains an object reference , that reference is released when assigning new values. You can not use the New keyword to create a new instance of any internal data types, can not create dependent objects.
objectexpression
Required. By the object name, other variables the same type of objects declared or returns the expression or function of the same object type method thereof.
Nothing
Optional. Objectvar sever associated with any of the specified object. If no other variable to point
Objectvar original objects referenced, it is assigned to Nothing releases all the system and memory resources associated with the object.
2, Description:
In order to ensure legal, objectvar must be consistent with the object being assigned to the object type.
Dim, Private, Public, ReDim, and Static statements only declare a variable reference object. Using
Before the Set statement to assign a specific object variable, the variable does not refer to any actual object.
The following example shows how to use Dim to declare an array of type Form1. Form1 not actually instances. Then use
Set a reference to an instance of Form1 assigning the newly created myChildForms variables. In MDI
Applications can use the code to create a subform.
Dim myChildForms(1 to 4) As Form1
Set myChildForms(1) = New Form1
Set myChildForms(2) = New Form1
Set myChildForms(3) = New Form1
Set myChildForms(4) = New Form1
Typically, when you use Set to assign an object reference variables, not for variables create a copy of the object, but the object is to create a reference. There can be multiple object variables refer to the same object. Because these variables only reference to the object, rather than a copy of the object, and therefore the reaction will object to any changes to the object variable references all. However, if the
Set statement using the New keyword, it would in effect create a new instance of the object.
3, Set Statement Example
This example uses the Set statement to assign an object reference variables. Text has assumed a point YourObject
Legitimate object properties.
Dim YourObject, MyObject, MyStr
Set MyObject = YourObject 'object reference assignment.
'MyObject and YourObject reference the same object.
YourObject.Text = "Hello World" 'initialization properties.
MyStr = MyObject.Text 'returns "Hello World".
'Disassociate. MyObject no longer referenced YourObject.
Set MyObject = Nothing 'release the object.
