Input: Base64 Encoded Excel File
What is Base64?
Base64 is a method of encoding binary data into ASCII characters to facilitate data transfer and storage.
What is Base64 Decoding?
Base64 decoding, at its core, is the process of converting Base64-encoded data back to its original binary format. The encoding scheme is reversed in this process, and characters from the set of 64 ASCII characters are transformed into binary representations. Base64 decoding recovers the original data and allows you to access, read, and use it as intended.
How Does Base64 Decoding Work?
Base64 decoding works by mapping characters from Base64-encoded text back to their binary values. The original binary data is then recreated by combining these binary values. The encoded data is returned to its pre-encoded state after this reverse transformation, ready for processing, storage, or transmission.
What is the Base64 to Excel File Converter?
The Base64 to Excel File Converter is a program that allows you to convert Base64-encoded data into .xls format.
How To Use the Online Base64 to XLS Decoder?
- Simply enter the Base64 encoded file in the Input field.
- The conversion time may vary depending on the size, so please wait until it is finished.
- You can download the decoded XLS file by clicking the Download button.
Is it Secure to Use Your Base64 to XLS Converter?
Absolutely. Our program operates entirely on the client side, which means all the conversion processes occur within your browser. No data is sent to our servers, ensuring that your information remains under your control and confidential throughout the conversion process.
Base64 Characters
Uppercase letters (A-Z), lowercase letters (a-z), digits (0-9), and two additional characters, typically “+” and “/”, comprise the set of 64 ASCII characters used in Base64 encoding. When the length of the binary data is not a multiple of three bytes, the “=” character is also used for padding.
