Convert octal integers (base 8) into standard decimal values (base 10). This variant defaults to batch mode, letting you paste multiple octal numbers separated by newlines to see the decimal translations instantly side-by-side.
Supported octal formats
The converter limits input to standard octal characters (0-7). You can include 0o prefixes, and the tool will safely ignore spaces or underscores in the text. Signed integers are supported by appending a leading + or -.
Error handling
Each line is calculated individually. If a line contains invalid characters—such as digits 8 or 9, letters, or decimals—that specific line outputs an inline error message while the rest of your batch finishes perfectly.
