Using Microsoft Excel to Convert XLSX to CSV

Microsoft Excel, a staple in data management, is the home of XLSX files. These files support data in rows or columns, charts, and mathematical functions, making them perfect for complex data operations. However, when it comes to data export and transfer, the CSV format comes into play. CSV stands for ‘comma-separated values’, and as the name suggests, it stores numeric and alphanumeric data in a simple text format, with commas acting as columns delimiter, making it more lightweight and universally readable. This distinction highlights the importance of choosing the right file format for your specific needs.

Converting XLSX files to this versatile format using Excel is a simple process. By simply opening your XLSX file in Excel and using the ‘Save As’ feature, you can save your file as a CSV format. Like any technical procedure, this process may encounter some hiccups. You might encounter issues such as data loss, formatting problems, and character encoding errors. Rest assured, we will guide you on how to overcome these potential obstacles.

Opening XLSX File in Excel

The first step towards converting your XLSX file to CSV format using Excel is to open your XLSX file. The file extension for the Open XML Spreadsheet format is XLSX. This format is utilized by Microsoft Excel. To open the file, you simply navigate to ‘File’ on the Excel menu, select ‘Open’, and then choose the XLSX file that you wish to convert.

You are now ready to convert your XLSX file to CSV format.

Saving as CSV Format

With your XLSX file open in Excel, converting it to CSV format is a breeze. You just have to follow these steps:

  1. Navigate to the ‘File’ menu and select ‘Save As’.
  2. In the ‘Save As’ dialog box that pops up, you’ll find a ‘Save as type’ option. Here, you need to select ‘CSV (comma delimited)’ from the dropdown list.
  3. Choose your desired location on your computer where you want the CSV file to be saved.
  4. Name your file appropriately, and then hit ‘Save’.
  5. And voila! You’ve successfully converted your XLSX file to CSV format.

Remember, this method converts only one sheet at a time. If your Excel workbook contains multiple separate sheets, you’ll have to repeat this process for each sheet.

What about issues during the conversion process? Let’s tackle those potential challenges.

Troubleshooting Common Issues

In an ideal world, all technical processes would go off without a hitch. Unfortunately, we’re not always that lucky. When converting XLSX files to CSV, you might face some issues. For instance, Excel might incorrectly change cell formats, such as converting text to number, leading to the loss of leading zeros in numeric codes. Also, if an XLSX file contains multiple tabs, Excel might only save the active tab to CSV, ignoring the other tabs in the workbook.

Don’t be discouraged by these minor setbacks. There are ways to remedy these issues. For instance, creating a ‘Dump Clipboard’ tool can help you avoid issues with Excel’s clipboard functionality, eliminating the need for a system reboot. In some instances, uninstalling third-party antivirus software such as Kaspersky could be necessary to avoid interference with Excel’s copy-paste functionality during conversion. By being aware of these potential issues and their solutions, you can ensure a smooth conversion process.

Converting XLSX to CSV on Linux CLI

If you’re a Linux user, don’t worry, we’ve got you covered too. There are various command-line tools that can be used on Linux to convert XLSX files to CSV format. These include:

  • ssconvert
  • LibreOffice
  • unoconv
  • xlsx2csv

Whether you’re dealing with a single file or a bunch of them, these tools have got you covered.

Let’s examine some of these tools and their usage.

Gnumeric Spreadsheet Program

The Gnumeric Spreadsheet Program is a powerful tool that allows for single and batch conversions of XLSX files to CSV format. Here are the steps to convert a single XLSX file to CSV format using Gnumeric:

  1. Open the Linux terminal.
  2. Use the apt-get command to install the Gnumeric repository.
  3. Once installed, use the ssconvert command to convert the XLSX file to CSV format.

What if you have multiple XLSX files that you want to convert? No problem. Gnumeric allows for the conversion of multiple XLSX files to CSV format in one go. By using the ‘find’ command in combination with ssconvert, you can convert all your XLSX files in a directory to CSV format with a single command. This ability to convert in batches makes Gnumeric an ideal tool for large-scale data conversion tasks.

xlsx2csv Converter

The xlsx2csv Converter is another handy tool for XLSX to CSV conversion on Linux. This tool is designed specifically for converting XLSX files to CSV format and offers flexibility by allowing for the conversion of either individual sheets or all sheets within an XLSX file.

To convert all the sheets in an XLSX file using xlsx2csv, you can use the command ‘xlsx2csv file.xlsx –all > all.csv’. If you want to convert a specific sheet, xlsx2csv uses the ‘-s’ flag followed by the sheet number. An example command would be ‘xlsx2csv file.xlsx -s 1 > sheet1.csv’. With these commands, you can easily tailor the conversion process to your specific needs.

csvkit Tool

The csvkit Tool is a Python library that simplifies the XLSX to CSV conversion process on Linux CLI. It offers the ‘in2csv’ command, which allows for the conversion of various tabular data formats into CSV. This includes formats like:

  • CSV
  • DBF
  • fixed-width
  • GeoJSON
  • JSON
  • ndjson
  • XLS
  • XLSX

This makes csvkit a versatile csv converter tool for data conversion and csv online processing.

Furthermore, the csvkit Tool includes several options for specifying input formats, defining schemas for fixed-width conversions, and managing Excel sheets. It can display Excel sheet names, convert data from specified sheets, and even write output from multiple Excel sheets either to one or separate CSV files. Plus, it includes a feature to reset sheet dimensions if the Excel file has incorrect worksheet settings. With these features, csvkit provides a comprehensive solution for XLSX to CSV conversion on Linux CLI.

Google Drive: Converting XLSX to CSV

Google Drive is more than just a cloud storage service. It can also be a handy tool for converting XLSX files to CSV format. By leveraging Google Sheets, an integral part of Google Drive, you can effortlessly convert your XLSX files to CSV format.

Let’s go through this process in a step-by-step manner.

Uploading XLSX File to Google Drive

The first step in this process is to upload the XLSX file to Google Drive. You can do this by following these steps:

  1. Log in to your Google Drive account.
  2. Click on ‘New’.
  3. Click on ‘File Upload’.
  4. Select the XLSX file you wish to convert.

For a more streamlined experience, you can set Google Drive to automatically convert uploaded Excel files to Google Sheets format. This can be done by checking the ‘Convert uploads’ option in the Settings menu.

Opening in Google Sheets

With your XLSX file uploaded to Google Drive, the next step is to open it in Google Sheets. This can be achieved by navigating to the uploaded file within your Google Drive, right-clicking on it, and selecting ‘Open with Google Sheets’.

The file will then open in a new tab, ready for you to edit and convert.

Exporting as CSV Format

After opening the XLSX file in Google Sheets, you’re now ready to export data as a CSV format. To do this, you need to navigate to the ‘File’ menu, go to ‘Download’, and then select ‘Comma-separated values (CSV)’. This will convert and download the file in CSV format.

Bear in mind that this process, similar to Excel, only converts the currently active sheet within the workbook to CSV. If your workbook contains multiple sheets, you’ll need to convert each sheet individually.

Also, when converting XLSX to CSV, formatting or formulas that are specific to Excel may not be retained in the CSV file. Hence, it’s recommended to check the data after conversion, especially if your XLSX file contains cells with commas or newlines, as these may affect the structure of the resulting CSV.
