“Python Convert Csv To Xlsx” ~ bbaz
Introduction
Data manipulation has become an essential part of business intelligence, and CSV (comma-separated values) is one of the most common file formats used to store and exchange data. However, this format may not always be suitable for data visualization, analysis or sharing. In these cases, it is necessary to convert CSV files to a more robust and flexible format such as XLSX (Microsoft Excel).Python is a powerful programming language that can be used for various tasks, including converting CSV files to XLSX with minimum effort. In this article, we will explore how to do just that.
CSV vs XLSX: A Brief Comparison
Before we dive into the technicalities of converting CSV to XLSX using Python, let us compare these two file formats briefly.CSV files are plain text files that consist of rows and columns separated by a delimiter, usually a comma or a semicolon. These files are lightweight and easy to create and manipulate. However, they lack some functionalities that XLSX files offer, such as formatting options, formulas, and multiple sheets support.On the other hand, XLSX files are binary files that can store data in a structured way using worksheets and workbooks with advanced formatting and formula options. However, they are complex and require specialized software such as Microsoft Excel to create and modify them.
Prerequisites
Before we proceed, you need to have the following installed:
- Python 3.x
- pandas library
- openpyxl library
Step 1: Importing Libraries
To start with the conversion process, we need to import relevant libraries.“`pythonimport pandas as pdfrom openpyxl.workbook import Workbook“`
Step 2: Reading the CSV File
The next step is to read the CSV file using pandas’ `read_csv()` function. We also need to specify the delimiter used in the CSV file, which might be either comma or semicolon, and the encoding type.“`pythondf = pd.read_csv(‘data.csv’, delimiter=’;’, encoding=’utf-8′)“`
Step 3: Creating an XLSX File
In this step, we will create a new XLSX file using the Workbook class from the openpyxl library.“`pythonwb = Workbook()ws = wb.active“`
Step 4: Writing Data to the XLSX File
Now, it’s time to write the data from the CSV file to our newly created XLSX file. We can do this using a for loop that iterates over each row of our pandas DataFrame and writes the values to the respective cells in the XLSX file.“`pythonfor r in dataframe_to_rows(df, index=False, header=True): ws.append(r)“`
Step 5: Saving the XLSX File
Finally, we need to save the XLSX file with the desired name and location.“`pythonwb.save(‘data.xlsx’)“`
Comparison Table
Here’s a quick comparison table summarizing the differences between CSV and XLSX files.
| CSV | XLSX | |
|---|---|---|
| File type | Plain text | Binary |
| File size | Small | Large |
| Data manipulation | Easy | Complex |
| Formatting options | No | Yes |
| Formulas support | No | Yes |
| Multiple sheets support | No | Yes |
Conclusion
In conclusion, converting CSV files to XLSX can be a daunting task if done manually, especially if the data is large and continuously updated. However, using Python and relevant libraries such as pandas and openpyxl, this process can be efficiently automated with just a few lines of code.While both CSV and XLSX file formats have different functionalities and use cases, XLSX’s advanced features make it an ideal option for data analysis and visualization.

Effortlessly converting CSV to XLSX with Python can be a useful skill for data analysts and programmers. Here are some common questions people ask about this process:
- What is the difference between CSV and XLSX?
- Why would I want to convert CSV to XLSX?
- How can I convert CSV to XLSX using Python?
- import pandas as pd
- df = pd.read_csv(mydata.csv) # read CSV file into a Pandas DataFrame
- df.to_excel(mydata.xlsx, index=False) # write DataFrame to an XLSX file
- Can I customize the conversion process?
- Are there any limitations or challenges to be aware of?
CSV (Comma Separated Values) is a simple file format used to store tabular data, where each row represents a record and each column represents a field. XLSX (Excel Spreadsheet) is a more complex file format that can store multiple sheets, formulas, charts, and other features.
Converting CSV to XLSX can allow you to take advantage of Excel’s advanced features, such as formatting, filtering, sorting, and data validation. XLSX files are also easier to share with others who use Excel or other spreadsheet software.
One way to convert CSV to XLSX with Python is to use the Pandas library, which provides a function called to_excel. Here is an example code snippet:
Yes, the to_excel function accepts many optional parameters that allow you to control the formatting, sheet name, header, footer, and other aspects of the output file. You can also use other Python libraries, such as openpyxl or xlsxwriter, to perform more advanced operations on XLSX files.
Yes, converting CSV to XLSX can cause some loss of data or formatting if the original CSV file contains non-ASCII characters, special symbols, or other unsupported features. It is also important to ensure that the CSV file follows a consistent structure and encoding, otherwise the conversion may fail or produce unexpected results.
