5 Simple Ways to Save Excel as CSV

When you work with Excel, you often need to transfer your data into a format that's easy to share or integrate with other software systems. CSV (Comma-Separated Values) files serve this purpose perfectly. These files are universally readable by most spreadsheet programs and database systems, which makes saving your Excel workbooks as CSV files a valuable skill to learn. In this guide, we'll explore five straightforward methods to convert your Excel data into CSV format, ensuring you can do so effortlessly and effectively.

Why Save Excel Files as CSV?

Before we dive into the methods, it’s worth understanding why CSV files are so prevalent:

• Portability: CSV files are text files, making them much smaller and easier to share.
• Compatibility: Almost every data manipulation software can read or write CSV files.
• Database Integration: Many databases can import or export data in CSV format, facilitating easier data transfer.
• Data Cleaning: If you’re preparing data for analysis, a CSV format can simplify the process by eliminating formatting issues.

Method 1: Using Excel’s Built-in Save As Feature

Excel offers a native feature to save files as CSV:

1. Open your Excel workbook.
2. Go to File > Save As.
3. Choose your save location.
4. Under File name, type the desired name for your CSV file.
5. From the Save as type dropdown, select CSV (Comma delimited) (*.csv).
6. Hit Save.

⚠️ Note: When you save an Excel file as CSV, you’ll lose all your formatting, macros, and formulas. Only the data will be preserved.

Method 2: Using VBA Script

If you frequently need to save files as CSV, creating a VBA script might be more efficient:

Sub SaveAsCSV()
    ‘This script saves the active workbook as CSV in the same location
    ActiveWorkbook.SaveAs FileFormat:=xlCSV, CreateBackup:=False
End Sub

To use this script:

1. Press Alt + F11 to open the VBA editor.
2. Insert a new module (Insert > Module).
3. Copy and paste the above code.
4. Run the macro when needed by selecting Developer > Macros > SaveAsCSV > Run.

Method 3: Using Power Query

Power Query, integrated into Excel, provides an advanced way to transform and save data:

1. Select Data > Get & Transform Data > Get Data or use the Power Query tab if available.
2. Import or connect to your Excel data.
3. Transform the data as needed using Power Query tools.
4. Go to File > Export > Export as CSV.

Method 4: External Tools

If you’re outside of Excel, using tools like Python or specialized data conversion software can be handy:

• Python: The pandas library makes it easy to read and write Excel files:

  import pandas as pd
  df = pd.read_excel(‘yourfile.xlsx’)
  df.to_csv(‘yourfile.csv’, index=False)

• Convertio: An online converter that can convert Excel to CSV among many other formats.
• Notepad++: Open your Excel file, copy data, and use the TextFX plug-in to format as CSV.

Method 5: Command Line or Batch Processing

For bulk conversion, command-line tools or batch processing can save time:

• LibreOffice: soffice –convert-to csv *.xls
• Power Shell: You can write scripts to convert multiple files:

  Get-ChildItem *.xlsx | % {
      newname = [System.IO.Path]::GetFileNameWithoutExtension(.Name) + “.csv”
      Import-Excel $.FullName | Export-CSV -Path $newname -NoTypeInformation
  }

Each of these methods has its place depending on your specific needs and the environment in which you work. Whether you're looking for simplicity, automation, or compatibility with other systems, one of these techniques will fit your requirement.

Wrap-Up

Converting Excel files to CSV is essential for data exchange, analysis, and integration. By learning these five methods, you’ll be well-equipped to handle this task regardless of your current workflow or software ecosystem. Remember, while CSV files are excellent for data sharing, they come with limitations like loss of formatting and formula calculation capabilities, so use them wisely. Here are some takeaways:

• Excel’s Save As feature is the most straightforward method, suitable for one-time conversions.
• VBA scripts are ideal for automating repetitive tasks within Excel.
• Power Query offers more complex data manipulation before conversion.
• External tools provide flexibility for users outside of Excel’s ecosystem.
• Batch processing is efficient for converting multiple files at once.

What are the disadvantages of using CSV files?

+

CSV files are primarily text-based, which means they can’t retain formatting, macros, or formulas from Excel. This can lead to data loss if these elements are critical for your workflow.

Can I undo the conversion from Excel to CSV?

+

No, once an Excel file is saved as CSV, the original formatting and functions are lost. However, if you still have the original Excel file, you can revert back to using that. If not, you’ll need to recreate or import the CSV back into Excel.

Which method is best for saving Excel as CSV when dealing with many files?

+

Command line or batch processing tools like PowerShell or LibreOffice’s conversion command are best for converting multiple Excel files to CSV in one go.
