'Convert XLS'  Used to convert XLSX to CSV Files

NOTE: A CSV file can be any character delimited file, see CSV File Definition for details.

Do you need software to convert XLSX To CSV (or CSV to XLSX)?  If so, we got just the tool you need. 'Convert XLS' can convert XLSX to CSV (as well as XLS, a fixed width text file, HTML or XML) 10 to 20 times faster than using MS Excel.  You can specify the delimitation character used in your CSV file, which is most commonly the comma. Furthermore, Unicode and other text encodings (ASCII, ANSI, UTF8 etc.) are supported.

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.  You can even move or delete the input files after processing.

  Converting From XLSX file to a CSV File

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.

     Specify the Original File Format.  In this case it is “[51] MS Open XML Excel Workbook (*.XLSX)”.

    Click on the Options button and choose the sheets, ranges and whether to include values or 'formulas and values' to convert.  Also within the Options button select the “CSV, TSV…” tab to choose what character you are using to distinguish each piece of data within each record for your output CSV file. By default the comma is used.

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\*.CSV").  Finally, specify the ‘Convert To File Format” target (output) file type.  In this case it may be one of two choices, “[6] Character Separated (*.CSV)” or “[23] Character Separated Unicode (*.csv)”.  Note that you will have more choices available if you choose the ‘MS Excel’ conversion method.

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

  Converting To XLSX file from a CSV file

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 csv files located in “C:\input folder\” then use “C:\input folder\*.ext” where ext is the extension used for the files.  Typically, *.ext will be *.csv but not always.

     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 File Format.  In this case it may be one of three choices, “[6] Character Separated (*.CSV)”, “[23] Character Separated Unicode (*.csv)” or “[25] Character Separated UTF-8 (*.csv)”.

    Are you using something other than a 'comma delimited csv file'? If so click on the OPTIONS button and then the “CSV, TSV…” tab to choose what character you are using to distinguish each piece of data within each record.  

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)”. Note that you will have more choices available if you choose the ‘MS Excel’ conversion method.

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

 

Command Line Examples: Conversion of XLSX To CSV

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 single worksheet within a XLSX (Open XML Excel Workbook) file to the most popular form of a CSV file, a comma delimited file as well as a Tab Delimited File (TSV).  It can be easily modified to convert from an Excel file to any character delimited CSV file.  Also in the first example we’ll show how to specify a specific range of cells within a sheet(s) to convert.

The second example shows how to convert multiple sheets within a single Excel file.  Creating a single and multi-file output is illustrated.

The third and final example shows how to convert one or more sheets within many XLSX files within a folder (and subfolders).

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 (Single Sheet Conversion) 

To convert a single XLSX file, C:\in\B.XLSX (Sheet named "LastSheet") to a comma delimited CSV file, C:\out\B.CSV using MS Excel conversion method, the following syntax would be used:

 

ConvertXLS.EXE /S"C:\in\B.XLSX" /F51 /N"LastSheet" /T"C:\out\B.CSV" /C6 /M1 /V

 

To do the same using the 'Convert XLS' conversion method (extremely fast and MS Excel not required) simply change the /M1 switch to /M2 as shown below:

 

ConvertXLS.EXE /S"C:\in\B.XLSX" /F51 /N"LastSheet" /T"C:\out\B.CSV" /C6 /M2 /V

 

If you want a tab (ASCII 9) delimited file instead of a comma delimited file simply adjust the /N switch:

 

ConvertXLS.EXE /S"C:\in\B.XLSX" /F51 /N"LastSheet^^9" /T"C:\out\B.CSV" /C6 /M2 /V

 

Change the 9 (tab character) in the example above to any character you want. Look at the ASCII Chart for numeric character equivalents. 

VERY IMPORTANT NOTE: Choosing the delimitation character is only possible when using the ‘Convert XLS’ (/M2) conversion method.

Building on the last example, say you want to specify a range, say A1:B10 within a sheet to convert. No problem, simply modify the /N switch as shown below:

ConvertXLS.EXE /S"C:\in\B.XLSX" /F51 /N"LastSheet^A1:B10^9" /T"C:\out\B.CSV" /C6 /M2 /V

 

Specifying ranges can be very powerful. For example if you want to only extract column N you can use “N:N” for the range.

 

Example 2 (Multiple Sheet Conversion) 

In example 1 we saw how the /N switch is used to specify the sheet/range to convert and what delimitation character to use in the character separated CSV file.  Here we build upon that and show how to specify more than one sheet to convert.

To convert a single XLSX file, C:\in\B.XLSX (Sheets named "LastSheet","FirstSheet", and "MidSheet") to one CSV file, C:\Out\B.CSV, the following syntax would be used:

 

ConvertXLS.EXE /S"C:\in\B.XLSX" /F51 /N"FirstSheet,LastSheet,MidSheet" /T"C:\Out\B.CSV" /C6 /M2 /V

 

After completion of this example the following file will be created containing all the data of the 3 sheets specified:

                C:\Out\B.CSV

 

To create several output files you can add the /U switch like so:

ConvertXLS.EXE /S"C:\in\B.XLSX" /F51 /N"FirstSheet,LastSheet,MidSheet" /T"C:\Out\B.CSV" /C6 /M2 /U  /V

 

After completion the output would be several files:

C:\Out\B-FirstSheet.CSV

C:\Out\B-MidSheet.CSV

C:\Out\B-LastSheet.CSV

 

VERY IMPORTANT NOTE: The /U switch is only applicable to the ‘Convert XLS’ (/M2) conversion method.  Using the ‘MS Excel’ (/M1) Conversion method always produces a multi-file output.

If FirstSheet, MidSheet, and LastSheet were indexed 1,2 and 4 respectively, the same results can be attained by setting /N To /N"1-2,4"

 

Example 3 (Multiple File/Folder Conversion) 

Say you wanted to convert the 2nd sheet (/N"2") regardless of what the sheet name might be, of all the XLSX files within the  “C:\in\” folder and subfolders (/R for recursive subfolders). To do this the syntax would be:

 

ConvertXLS.EXE /S"C:\in\*.XLSX" /F51 /N"2" /T"C:\out\*.CSV" /C6 /M2 /R /V

 

The example above can be modified to have the resulting files placed in the same folder as the original files.  By specifying the /G switch and removing the /T switch as shown below:

 

ConvertXLS.EXE /S"C:\in\*.XLSX" /F51 /N"2" /G /C6 /M2 /R /V

 

In the last two examples, you can also use the /M1 switch to specify the ‘MS Excel’ conversion method.


  • 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 /C6 switch specifies that the target (output) file to be a CSV file whereas the /F51 switch specifies the original (input file) is a XLSX 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"

Sheet:  Only used when an Excel file is the original file. Use "*" or "" for all sheets. You can use names of sheets, or the numeric index. If using numeric indices, you can specify ranges of sheets (i.e. "1,4,10-20" and "4-10,9" etc.). Range and DelimChar are optional.

Range: You could optionally specify a range, say if you only wanted to convert a portion of the input file.  Use the same syntax as an Excel range (e.g. A1:B10).

DelimChar: is for specifying the ASCII value of the delimitation character used in a CSV file. 44 for comma, 124 for Bar “|”, 9 for the tab etc.

FixedWidth: Here you can specify how to import/export a fixed width text file.  Not used in this example.

  •  /H If converting from XLSX to something else and using the ‘Convert XLS’ conversion method (/M2) you can optionally specify to include values along with formula, much like "MS Excel" conversion method does.

  •  /U If converting an XLSX file with multiple sheets specified, the /U switch will generate multiple files instead of a single file.

  • 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.
