'Convert XLS'  Used to convert XLS to XLSX Files

Do you need software to convert XLS to XLSX?  If so, we have 'the tool'. 'Convert XLS' can convert Open XML Excel Workbook to XLS (as well as XML, CSV, or a fixed width text file) 10 to 20 times faster than using MS Excel.  In fact you can do these conversions with or without MS Excel giving you great flexibility.  Using MS Excel is not as fast, but it gives you many more file types that you can convert to (such as PRN, DBF, WKS etc).

Furthermore, all our conversion tools allow you to automate the process by using the built in scheduler, command line (batch files, command prompt etc.), or for you programmers a COM/ActiveX interface.

Convert XLS to XLSX with the User Interface

First we show what conversions are possible with XLSX files, then we discuss specific directions for how to use the programs user interface.

What Conversions Are Possible With XLSX Files

Below we show you what you can convert XLSX files to/from when using ‘Convert XLS’, click on the link for more details:

Convert from XLS TO these file types Convert To XLS file FROM these file types

 

 ** Requires the use of the ‘MS Excel’ conversion method.

  Converting From XLS file to a different file type such as XLSX

1. Select the ‘Convert Files’ Action To Do

2. Select the input file path. For a whole folder be certain to use the *.ext format.  For example if you want to convert the folder of xls files located in “C:\input folder\” then use “C:\input folder\*.xls”.

     Choose the ‘Convert XLS’ conversion method. You can also select the MS Excel conversion method if you have MS Excel installed.

     If you are using the ‘Convert XLS’ conversion method, specify the Original File Format.  In this case it is “[-4143] Microsoft Excel Workbook (*.XLS)”.

    Click on the Options button and choose the sheets, ranges and whether to include values or 'formulas and values' to convert.

3.  Now specify the Target (output) file path. If you are doing a whole folder, then specify the whole folder using the “*.ext” format (for example "c:\output\*.XLSX").  Finally, specify the ‘Convert To File Format” target (output) file type.  In this case it is “[51] MS Open XML Excel Workbook (*.XLSX)”.

4. Click the CONVERT button on the tool bar to start converting.

  Converting To XLS file from a different file type such as XLSX

1.  Select the ‘Convert Files’ Action To Do

2.  Select the input file path. For a whole folder be certain to use the *.ext format.  For example if you want to convert the folder of XLSX files located in “C:\input folder\” then use “C:\input folder\*.XLSX".

    Choose either ‘Convert XLS’ or ‘MS Excel’ conversion method.  The ‘Convert XLS’ conversion method can be 10-20 times faster than the ‘MS Excel’ conversion method.  The ‘MS Excel’ conversion method however, can convert any file MS Excel can open.

    If you are using the ‘Convert XLS’ conversion method, specify the Original (input) File Format.  In this case it is “[51] MS Open XML Excel Workbook (*.XLSX)”. Since your input file is an Excel file you may specify the sheet(s) and range you want by clicking on the Options button.

3.  Now specify the Target (output) file path. If you are doing a whole folder, then specify the whole folder using the “*.ext” format (for example "C:\Output\*.XLS").  Finally, specify the ‘Convert To File Format” target (output) file type.  In this case it will be “[-4143] Microsoft Excel Workbook (*.XLS)”.

4. Click the CONVERT button on the tool bar to start converting.

 

 

Command Line Examples: Conversion of XLS to XLSX

NOTE: 'Convert XLS' can be used simply with the graphical user interface (GUI).  If you've never heard of 'Command Line' before, we would recommend not reading this section and instead download and try the software.

This is just a sample from the documentation.   If you have trouble running these examples please see Using the Command Helpful Hints For Creating a Command Line within the documentation.

 

The first example shows how to convert a XLS file to an XLSX file. 

Each switch shown in blue is described in detail below the examples. It is highly recommended you review each switches description before implementing the example, thereby giving you the full power of ‘Convert XLS’.

Example 1 (XLS File to XLSX) 

To convert a single XLS file,  “C:\in\input.XLS” to an XLSX file located in the  “C:\Out\” folder, the following syntax would be used:

 

  ConvertXLS.EXE /S"C:\in\input.XLS"  /T "C:\Out\output.XLSX" /F-4143  /C51 /M2 /V

 

To convert a whole folder (and subfolders) of XLS files located in  C:\in\*.XLS  to XLSX files to be placed within c:\Out\ folder, the following syntax would be used:

  ConvertXLS.EXE /S"C:\in\*.XLS"  /T "C:\out\*.XLSX" /F-4143  /C51 /M2 /R /V

 

The /G switch can be used to tell ‘Convert XLS’ to simply place each output file in the same folder as each input file. Therefore the command line above is equivalent to the command line below:

  ConvertXLS.EXE /S"C:\in\*.XLS"  /G  /F-4143  /C51 /M2 /R /V

 

You may simply want to convert a whole folder and its subfolders and place the output into a separate folder/drive. In which case use this syntax:

  ConvertXLS.EXE /S"C:\in\*.XLS"  /T "C:\Out\*.XLSX"   /F-4143  /C51 /M2 /R /V


  • The /S and /T switches above specify Source (input) and Target (output) path respectively and are both required when converting a single file.  It is always a good idea to use double quotes around the path especially if there are space characters within the path.

  • The /C51 switch specifies that the target (output) file to be an XLSX file whereas the /F-4143 switch specifies the original (input file) is an XLS file.  See Excel Conversion File Type Constants (documentation) for all possible values for /C and /F.

  • The /M2 switch tells it to use the ‘Convert XLS’ conversion method which is exceptionally fast. Note the /M1 switch could have been used to specify the ‘MS Excel’ conversion method which is a bit slower and requires MS Excel.

  • The /R switch tells it to search the original folder and its subfolders for files to convert.

  • /G switch can be used to tell ‘Convert XLS’ to simply place each output file in the same folder as each input file.

  • /N"{Sheet^Range^DelimChar^FixedWidth^X}"  Is used when converting to/from an Excel, CSV or fixed width text file. It specifies which Sheets to convert, what Range to convert and what delimitation/separation character to use, and the method to import export to a fixed width text file.  The syntax for this parameter is critical, the items are separated by a carrot character "^".  If you do not include Sheet, Range or DelimChar by leaving them blank they will default to all sheets, all used ranges and the comma delimitation character.  Be certain to include the double quotation character around this parameter like: /N"Apples,Oranges^A2:B20^9"

  • The /V (for Verbose) switch is used to give instant feedback by having the program report the status of the conversion with a message box.  You can remove this once you have perfected your command line specification.  You can also (or instead of /V) create a Log file that will contain the results of the conversion by using the /L switch.

Note: It is highly encouraged that you use the Verbose (/V) switch initially to see what the status of your conversion is and to help you perfect your command line.  When in verbose mode the program will tell you what went wrong or right with your command line using message boxes.
