Do you need software to convert XLSX To CSV (or convert 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 the CSV file (most often the comma character). Furthermore, Unicode and other text encodings (ASCII, ANSI, UTF8 etc.) are supported.
Our tool does not need MS Excel, although you can optionally specify to use it. For those planning on using a server, this can be especially helpful for security enhancement.
All our conversion tools allow you to automate the process by using:
If you click the ADD button, a
'Conversion Item' is added to the 'task list' at the bottom of the user
interface. You can add as many 'conversion tasks' as you want, and
save the 'Conversion Job' file for use at a later time. See
the File menu for saving and restoring 'Conversion Jobs'.
'Convert XLS' can be especially helpful if you require complicated file conversion jobs done regularly. By saving and recalling a conversion job file, 'Convert XLS' quickly remembers all the file conversion tasks and their details.
Note: The same 'conversion job' file discussed above can be specified in the command line by using the /J switch. For example:
ConvertXLS.exe /J"C:\Conversion Jobs\Convert-XLSX-to-CSV-Command-Line.SII"

NOTE: After installation, you can find simple batch files (e.g. XLSXtoCSV.bat and XLStoCSV.bat) for quick and easy use by going to Start\All Programs\Convert XLS\Example Batch Files. These will work without modification provided the installation was in the default folder. Email us at if you have any questions or need additional examples. We will get you up and running fast!
Although we'll discuss the use of the command line here, it's only to give you a taste. For the full, accurate, and up to date information see the 'Convert XLS' command line documentation. If you have trouble running these examples see Helpful Hints For Creating a Command Line.
There are two approaches to using the command line:
A 'Conversion Job' is easily built using the 'Convert XLS' graphical user interface. All the details of the job are saved in a single conversion job file (e.g. 'c:\myjobs\Do-Multi-Step-Conversion.SII). Specifying a conversion job file with the command line is very easy by using the /J switch. You can have hundreds or thousands of tasks specified in the conversion job file, all of which will get executed in one fell swoop. For example:
ConvertXLS.EXE /J"D:\Job Files\Convert XLSX to CSV.SII"
Specifying a single conversion task requires a bit more effort, but does not require
the prior creation of a 'Conversion Job' file.
The first example below 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 a XLSX 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 workbook. 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 at the bottom of this page. It is highly recommended you review each switches description before implementing the example, thereby giving you the full power of 'Convert XLS'.
To convert a single XLSX file, C:\in\Bell.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\Bell.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) change the /M1 switch to /M2 as shown below:
ConvertXLS.EXE /S"C:\in\Bell.XLSX" /F51 /N"LastSheet" /T"C:\out\B.CSV" /C6 /M2
If you want a tab (ASCII 9) delimited file instead of a comma delimited file adjust the /N switch:
ConvertXLS.EXE /S"C:\in\Bell.XLSX" /F51 /N"LastSheet^^9" /T"C:\out\B.CSV" /C6 /M2
Change the 9 (tab character) in the example above to any character you want. Look at the ASCII chart for numeric character equivalents.
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\Bell.XLSX" /F51 /N"LastSheet^A1:B10^9" /T"C:\out\B.CSV" /C6 /M2
Specifying ranges can be very powerful. For example if you want to only extract column N you can use "N:N" for the range.
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\Bell.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\Bell.XLSX" /F51 /N"FirstSheet,LastSheet,MidSheet" /T"C:\Out\B.CSV" /C6 /M2
After completion of this example the following file will be created containing all the data of the 3 sheets specified:
To create several output files you can add the /U switch like so:
ConvertXLS.EXE /S"C:\in\Bell.XLSX" /F51 /N"FirstSheet,LastSheet,MidSheet" /T"C:\Out\B.CSV" /C6 /M2 /U
After completion the output would be several files:
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".
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 sub-folders (/R for recursive sub-folders). To do this the syntax would be:
ConvertXLS.EXE /S"C:\in\*.XLSX" /F51 /N"2" /T"C:\out\*.CSV" /C6 /M2 /R
The example above can be modified to have the resulting files placed in the same folder as the input 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
In the last two examples, you can also use the /M1 switch to specify the 'MS Excel' conversion method.
Sheet: Only used when an Excel file is the input 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.
