'Convert XLS' is 10-20 times faster than using Excel. It also allows for the saving and restoring of complex 'conversion jobs'. Specify a 'conversion job' within the command line or Windows scheduler and take a break.
Power users: Command line capability is fundamental to ALL of our software tools. Example batch files are installed ready for testing and modification. We are always here to help you implement our software.
Moving or deleting files while converting CSV to XLSX files is no problem. This makes unattended conversion of whole folders a no brainer.
If you need to manipulate CSV, XLSX, TXT file data, 'Convert XLS' comes with many features including:

Do you need software to convert CSV To XLSX (or convert XLSX to CSV)? If so, we got just the tool you need. 'Convert XLS' can convert CSV to XLSX (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-CSV-to-XLSX-Command-Line.SII"

NOTE: After installation, you can find a simple batch file CSVtoXLSX.bat for quick and easy use by going to Start\All Programs\Convert XLS\Example Batch Files. This 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 more effort, but does not require the prior creation of a 'Conversion Job' file.
The first example shows how to convert the most popular form of a CSV file, a comma delimited file, to an Excel Microsoft Office Open XML file. The second example shows how to convert any character delimited (tab, bar, semicolon etc.).
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'.
To convert a single comma delimited CSV file, "C:\in\input.CSV" to an Excel (XLSX) file located in the "C:\Out\" folder, the following syntax would be used:
ConvertXLS.EXE /S"C:\in\input.CSV" /T "C:\Out\output.XLSX" /C51 /F6 /M2 /V
To convert a whole folder (and sub-folders) of comma delimited CSV files, C:\in\*.CSV to XLSX files located in the D:\Out\ folder, the following syntax would be used:
ConvertXLS.EXE /S"C:\in\*.CSV" /T "C:\out\*.XLSX" /C51/F6 /M2 /R
The /G switch can be used to tell 'Convert XLS' to 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\*.CSV" /G /C51 /F6 /M2 /R
You may want to convert a whole folder and its sub-folders and place the output into a separate folder/drive. In which case use this syntax:
ConvertXLS.EXE /S"C:\in\*.CSV" /T "C:\Out\*.XLSX" /C51 /F6 /M2 /R
The next example can be adapted to convert any character delimited text (CSV) file. Say we have a bar "|" delmited text file that looks like this:
Our goal is to convert it to an Excel (XLSX) file. The bar character has an ASCII equivalent of 124 therefore they syntax would be like this:
ConvertXLS.EXE /S"C:\in\bar_delimited.txt" /T "C:\Out\Final.XLSX" /C51 /F6 /M2 /N"^^124"
If we had a tab delimited file we would change the 124 in the above examples with ASCII equivalent of the tab character, 9. If you are not sure what the numeric equivalent of your separation character is, go to the Options button and click on the "CSV,TSV " tab within the user interface. Of course the examples above can be adapted to do whole folders and sub-folders similar to what we did in Example 1.
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.
