Boolean truth table

Enumerate a bounded Boolean truth table using an explicit expression parser, with a downloadable CSV.

Your input

Outputs are cleared when the input changes.

Result

Enter your data or use the example, then run the tool.

Worked example

A AND NOT B is true only when A is true and B is false.

A OR NOT A is true for every row. An unclosed parenthesis is rejected.

Method

A tokenizer and precedence parser build the expression; every combination of the variables is evaluated.

CSV uses 0/1 and preserves the variable columns; no JavaScript eval is used.

Limits

At most 8 variables, 256 rows, 4,096 UTF-8 bytes and 64 nesting levels.

Not a general JavaScript runner, minimizer or formal proof assistant; only the documented grammar is accepted.
