Instructions

Software Usage Instructions

Single Conversion Mode

Enter an octal number directly in the input box (e.g., 755, 644, 1234). The system will display the corresponding binary result in real time, along with the decimal value and binary digit count.

Batch Text Conversion Mode

Enter one octal number per line in the text box. Comments are supported (lines starting with #). Click the "Start Batch Conversion" button to process them in bulk. After processing is complete, you can view detailed results and export a CSV file.

Batch File Conversion Mode

Upload a text file containing octal numbers (supports .txt and .csv formats), with one number per line. The system will preview the file content and perform batch conversion. After processing is complete, you can export the conversion results.

Conversion Rules: Each octal digit corresponds to 3 binary digits: 0→000, 1→001, 2→010, 3→011, 4→100, 5→101, 6→110, 7→111

FAQ

The octal number system uses only the 8 digits 0-7 and cannot contain 8, 9, or other characters. If the input contains invalid characters, the system will display an error.

When converting octal to binary, each octal digit corresponds to 3 binary digits. The system automatically removes leading zeros while keeping significant digits, so the result may have more digits than the original number.

In batch conversion mode, you can use lines starting with # as comments, and these lines will be skipped automatically. Blank lines will also be ignored and will not affect the conversion results.

Text files in .txt and .csv formats are supported, with one octal number per line. It is recommended that the file size not exceed 10MB; processing may take longer if there are too many lines.

Yes. After batch conversion is complete, you can click the "Export Results" button to save the conversion results as a CSV file, including detailed information such as the original octal numbers, converted binary numbers, and decimal values.

The system will automatically detect invalid input and mark it as an error in the results, while displaying the specific reason for the error. During batch processing, invalid data will not affect the conversion of other valid data.
