How to Read and Convert a Binary File to CSV in Python? – Be on the Right Side of Change (2024)
To read a binary file, use the open('rb') function within a context manager (with keyword) and read its content into a string variable using f.readlines(). You can then convert the string to a CSV using various approaches such as the csv module.
Here’s an example to read the binary file 'my_file.man' into your Python script:
with open('my_file.man', 'rb') as f: content = f.readlines() print(content)
Per default, Python’s built-in open() function opens a text file. If you want to open a binary file, you need to add the 'b' character to the optional mode string argument.
After you’ve converted the data to the comma-separated values (CSV) format demanded by your application, you can write the string to a file using either the print() function with file argument or the standard file.write() approach.
To change the delimiter of a CSV file while writing into it, we can specify the desired delimiter when creating the CSV writer object. In Python, we can achieve this using the csv. writer() function from the csv module.
assigned array as num=[3,6,9,12,18] to get the array in byte format. use byte array(). To read the written array from the given file, we have used the same file i.e., file=open(“array”, “rb”). rb used to read the array from the file.
In Python, you can simply use the bin() function to convert from a decimal value to its corresponding binary value. Similarly, the int() function to convert a binary to its decimal value.
A CSV file is a straightforward yet powerful data storage and manipulation tool. At its core, it is structured into rows and columns, using commas as delimiters to separate individual data points.
Reading CSV files is possible in pandas as well. It is highly recommended if you have a lot of data to analyze. pandas is an open-source Python library that provides high performance data analysis tools and easy to use data structures.
The open() function is used to open the file in binary mode ('rb'). Then, you can use struct.unpack() to read specific data types from the file based on the format string. The format string specifies the byte order, size, and type of the data you want to read.
We can use the base64 command to generate a human-readable text file from binary data. base64 is used for both Base64 encoding and decoding. If we use it without any options, it encodes the input. Its -d option is for decoding the encoded data.
We can convert the list to a CSV file by using NumPy's savetxt() function. The savetxt() function save an array to a text file. We can also use the savetxt() function to save the data into a CSV file.
Answer. The difference between a binary file and CSV file is that binary files are used for storing complex data in a non-human-readable format and they store data in a sequence of bytes, while CSV files are plain text files used for storing structured tabular data in a human-readable text format.
First, you need to add a file for conversion: drag & drop your BIN file or click inside the white area for choose a file.Then click the "Convert" button. When BIN to XLSX conversion is completed, you can download your result file.
