Convert decimal integers (base 10) to their octal representation (base 8). This streamlined variant forces batch processing on, letting you map large lists of base 10 values at once.
Paste your decimal values into the input pane. The converted octal outputs update live on the right.
Supported formatting
Valid inputs use digits 0-9 along with optional leading signs (+ or -). Underscores and internal spaces are stripped automatically, so numbers formatted like 12 345 are perfectly fine. Decimals or scientific notations will return an error.
Batch processing
Batch mode handles each line independently. An error on one line won’t halt conversion for the rest. Any blank lines are ignored or mirrored cleanly, keeping your output perfectly aligned with your input.
Octal output
The tool calculates standard base 8 values using digits 0-7. Outputs are provided raw without a 0o prefix. Negative signs are carried over directly from the input.
