How to Convert XLS to CSV

Stuck with an Excel file that won’t upload because it’s not in CSV format? Many tools and systems require CSV, leaving XLS files useless until converted. This small roadblock can waste hours if you don’t know the right steps. 

This guide on how to convert XLS to CSV will help fix that. With simple methods and clear tips, you can move your data smoothly. 

No need for complex tools or technical skills — just straightforward ways to turn Excel files into ready-to-use CSV format without the usual hassle. Let’s get started!

Why Would You Need to Convert XLS to CSV?

Many times, you may wonder why you even need to convert XLS to CSV. Here are important reasons that show how this simple step can make your tasks easier. Using an Excel or XLS tool can help you quickly convert your file to the desired format."

Easier Data Sharing Across Platforms

Converting XLS to CSV helps you share data with people or tools that don’t use Excel. CSV files are supported by many systems, making it easier for you to move your data without worrying about compatibility issues or complex file types.

Better Compatibility With Software

Many programs, especially databases and web apps, prefer CSV files over XLS. When you convert XLS to CSV, you make sure your data can be used smoothly across different software tools. Thus saving you time and avoiding errors during file uploads.

Smaller File Size for Faster Uploads

XLS files often carry extra formatting, making them large. CSV files, on the other hand, are plain text and much smaller. Converting XLS to CSV helps you upload files faster, especially when dealing with big datasets or slow internet connections.

Removing Unneeded Formatting

Sometimes, formatting in Excel is not needed and even causes issues. When you convert XLS to CSV, you strip away colors, fonts, and other styles, leaving only the clean data. This makes your files simpler and easier to handle for many systems.

Preparing Data for Automation

Many automated systems and scripts work best with CSV files. Converting XLS to CSV helps you prepare your data for smooth use in automated workflows. Thus making sure the file structure is simple, lightweight, and easy for systems to read.

How to Convert an XLS File to CSV Using Microsoft Excel

Converting an XLS file to CSV using Microsoft Excel may seem tricky at first, but it becomes easy when you follow these simple points. These clear steps will help you finish the task smoothly and avoid mistakes that could affect your data or file quality.

Open Your XLS File in Excel

First, launch Excel and open the XLS file you want to convert. Make sure all your data looks correct before moving forward. It’s smart to check for hidden columns, filters, or notes that you may want to remove before saving as CSV.

Select ‘Save As’ from the Menu

Once your file is ready, go to the “File” menu and choose “Save As.” This option lets you pick a new file type without changing your original Excel file. Make sure to select a folder location where you want the CSV saved.

Choose CSV Format from File Types

In the “Save As” window, look for the dropdown under “Save as type.” Select “CSV (Comma delimited)” or another CSV option that fits your needs. This step tells Excel to save the file in a simple, plain-text format that most systems understand.

Save Only the Active Sheet

Remember, Excel only saves the active sheet when converting to CSV. If you need other sheets saved, you must repeat the steps for each one. Check the sheet you’re working on and make sure it’s the right one before clicking “Save.”

Check the Saved CSV File

After saving, open the CSV file in a text editor or Excel to review it. Make sure your data looks clean and accurate. Look out for missing entries, strange characters, or changes in date formats that sometimes happen during the conversion process.

How to Convert an XLS File to CSV With Online Tools

Many people prefer using online tools when they want to convert an XLS file to CSV quickly. Here’s how to convert XLS to CSV online:

Choose a Trusted Online Converter

Start by picking a trusted online converter. Look for well-known tools with good reviews to avoid risks. Some popular choices include Bank Statement Converter, Zamzar, and Convertio. Using a reliable platform ensures your file stays safe and the conversion process runs smoothly without any unexpected problems or data loss.

Upload Your XLS File

Once you’ve selected a tool, upload your XLS file. Most tools let you drag and drop the file or use a file picker button. Make sure the correct file is uploaded before moving forward. Double-check the name or preview if available to avoid uploading the wrong file by mistake.

Select CSV as Output Format

After uploading, choose CSV as your output format. Most online converters support several formats, so picking the right one is important. This tells the tool you want your Excel data saved as a CSV. Carefully check that you’ve selected CSV to avoid having to redo the process later.

Start the Conversion Process

Click the convert button to begin the process. Depending on the file size and tool, the conversion may take a few seconds or minutes. Stay patient and let the tool finish working. Avoid closing the browser window or refreshing the page, as this might interrupt the process.

Download and Check the CSV File

Once the conversion is done, download your new CSV file. Open it to check if the data looks right and everything is converted properly. Look for errors, missing rows, or formatting changes. Taking a moment to review helps ensure you don’t run into problems when using the file later.

How to Convert Multiple Sheets in an Excel Workbook to CSV

Converting multiple sheets in an Excel workbook to CSV can feel tricky, but it’s doable with the right approach. These points will help guide you step by step.

Save Each Sheet Separately

Excel saves only the active sheet when exporting to CSV. You need to open each sheet, go to “Save As,” and save it individually as a CSV file. Repeat this for every sheet you want converted, making sure you label each file clearly to avoid confusion later.

Use Excel VBA for Automation

If you have many sheets, using Excel’s VBA (Visual Basic for Applications) can help automate the process. A small VBA script can loop through each sheet and save it as a separate CSV file. Thus saving you time and reducing manual effort when handling large workbooks.

Try Third-Party Tools

Several third-party tools can batch-convert Excel sheets to CSV files. These tools let you select the entire workbook and automatically split the sheets into separate CSV files. Choose a reliable program with good reviews, and always test it first on non-critical data before using it widely.

Use Python or Scripting

For advanced users, a Python script with libraries like pandas or openpyxl can automate this task. The script reads all sheets from the Excel file and saves each one as a CSV. This method works well for large data tasks and offers full control over the output.

Double-Check Converted Files

After converting, check each CSV file carefully. Make sure all rows and columns were saved correctly and that no data was lost. Pay attention to naming and folder structure so you can easily organize and access your files later without any mix-ups or missing content.

What Are Common Mistakes to Avoid When Converting Excel Files to CSV?

Converting Excel files to CSV may seem simple, but small mistakes can cause big problems. These important points will help you avoid common errors and keep your data safe.

Ignoring Extra Sheets in the Workbook

Remember, Excel only saves the active sheet when converting to CSV. Many people forget this and assume all sheets are included. Always check if you need to save other sheets separately, repeating the save process for each one to avoid missing important data in your CSV files.

Losing Special Characters or Accents

When converting, using the wrong encoding can cause special characters or accents to break. Always choose the CSV UTF-8 format if your file has non-English characters. This keeps your data clean and avoids confusion when you or others open the CSV later in different software or systems.

Overlooking Leading Zeros in Numbers

Excel sometimes drops leading zeros in numbers like ZIP codes or ID numbers when saving as CSV. To prevent this, set the cell format to text before conversion. This simple step helps keep your numbers accurate and avoids major issues when importing the CSV elsewhere.

Forgetting to Check Date Formats

Date formats can change during conversion depending on system settings. Before saving, review how dates appear in Excel and adjust the format if needed. After conversion, open the CSV and double-check to ensure your dates display correctly and haven’t shifted or changed unexpectedly.

Not Reviewing the CSV Output

Many skip the final review after saving the CSV file. Always open the file in a text editor or Excel to check for missing rows, strange symbols, or cut-off data. A quick review helps catch small errors early, saving you from bigger problems later.
