Common Questions
What is pseudocode and why should I use a Pseudocode Generator?
Pseudocode is a plain-language description of an algorithm's steps that uses structured conventions to bridge the gap between natural language and actual programming code. Our Pseudocode Generator helps you instantly convert natural language descriptions or existing code (JavaScript, Python, C++, Java) into properly formatted, academic-standard pseudocode—saving hours of manual writing and ensuring consistency for exams, documentation, and assignments.
What input methods does this tool support?
Our tool offers 5 powerful input methods: Natural Language to Pseudocode (describe your algorithm in plain English), Code to Pseudocode (convert JavaScript, Python, C++, or Java code), Visual Builder (drag-and-drop block-based construction), Algorithm Templates (pre-built templates for sorting, searching, and classic algorithms), and Flowchart Generator (visualize pseudocode as flowchart diagrams). Each method outputs properly formatted, syntax-highlighted pseudocode.
Which programming languages can be converted to pseudocode?
Our Code to Pseudocode converter supports JavaScript, Python, C++, and Java. The tool intelligently detects the language (or you can manually select it), then parses common constructs like loops (for, while), conditionals (if/else), functions, input/output statements, and variable assignments—transforming them into clean, structured pseudocode following standard academic conventions.
What pseudocode syntax styles are available?
Choose from 4 professional syntax styles: Academic Standard (START/END, INPUT, OUTPUT, IF...THEN...END IF), GCSE/A-Level UK Style (commonly used in British examinations), AP CS Style (Advanced Placement Computer Science format), and Pascal-like Style (BEGIN/END blocks). All styles support proper indentation, keyword highlighting, and consistent formatting for exams and documentation.
How does the Visual Builder work?
The Visual Builder provides a drag-and-drop interface where you click on building blocks (Start, End, Input, Output, Process, If, Else, For, While, Function, Return, Comment) to construct your algorithm step-by-step. Each block can be customized with your own variables and conditions. As you build, the pseudocode is generated in real-time, making it perfect for beginners and those who prefer visual construction over typing.
What algorithm templates are included?
We provide 15+ pre-built algorithm templates covering: Sorting (Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort), Searching (Linear Search, Binary Search), Math (Factorial, Fibonacci, Prime Check, GCD), and Data Structures (Stack Push/Pop, Queue Operations). Each template includes complexity notation (Big-O) and can be customized/exported instantly. Perfect for learning and exam preparation.
Can I generate flowcharts from pseudocode?
Yes! The Flowchart tab converts your pseudocode into visual flowchart diagrams using standard shapes: Ovals for Start/End, Rectangles for Processes, Diamonds for Decisions (IF/WHILE), and Parallelograms for Input/Output. You can zoom, pan, and download the flowchart as a PNG image—perfect for documentation, presentations, or exam submissions.
What does the Error Detection feature do?
Our intelligent Error Detection scans your pseudocode for common structural issues including: Unclosed blocks (missing END IF, END FOR, END WHILE), Mismatched structures (extra END statements), and Missing procedure/function endings. When errors are detected, you'll see a clear summary with the specific issue and location, helping you write syntactically correct pseudocode every time.
What export options are available?
Export your pseudocode in multiple formats: TXT (plain text for any editor), PDF (formatted document for printing/submission), DOCX (Microsoft Word compatible), PNG Flowchart (visual diagram export), and Copy to Clipboard (instant paste anywhere). The tool also provides a Line-by-Line Explanation feature that explains what each line of pseudocode does in plain English—great for studying and teaching.
Is my data private and does it work offline?
100% Private & Offline. All conversions, error detection, and flowchart generation happen locally in your browser using JavaScript. Your code, algorithms, and descriptions are never uploaded to any server. Once the page loads, you can disconnect from the internet and continue using the tool—making it completely safe for sensitive academic work, proprietary algorithms, or exam preparation in restricted environments.
