Code Generator
Describe the behavior you want. The explanation follows the language of this page.
Describe the task, choose a language, and generate.
The result may have been cut short. Try a smaller request.
What you get from a code request
Describe what the code should do and get a block you can copy, plus a short explanation of how to run it. The explanation follows the language of this page. The programming language is your choice: Python, JavaScript, TypeScript, Go, Rust, Java, C++, HTML, CSS, SQL, Bash, or automatic.
Ask for a function or a small program. “Read a CSV and count empty cells in each column” is a clear Python task. A request to build an entire product is too wide for one reply, and the result will be a sketch rather than a finished app.
Read the code before you run it. The explanation says how to start it, not that it is safe for untrusted data or production. The page refuses requests for malware, exploits, or credential theft.
How to generate code from a description
Say what it should do
Include inputs, outputs, and the edge you care about. “Count empty cells per column” is better than “help with a spreadsheet”.
Choose a language
Pick the one you will run, or leave automatic if you do not mind the choice. SQL belongs here when you want a query, Bash when you want a command.
Generate and read both parts
The code is in a block you can copy. Under it, a short explanation covers what it does and how to run it, in this page’s language.
Run it on sample data
Try it on a small file or a toy table before real data. If the explanation and the code disagree, trust a test, not the paragraph.
Requests that fit one reply
A Python function for a CSV
“Write a Python function that reads a CSV and counts empty cells in each column.” You should get a function, the imports it needs, and a note on how to call it with a path.
A SQL query you can adapt
“Select orders from the last 7 days with a missing invoice number, assuming table orders and columns created_at and invoice_number.” Name the table and columns so the query matches your schema.
A small JavaScript helper
“A function that groups an array of objects by a key and returns counts.” Choose JavaScript or TypeScript. The explanation on a Korean or Japanese page is in that language, while the code stays code.
Tips for code you can actually run
- Name the language, the input, and the output. Those three decide whether the snippet fits.
- Mention versions only if you need them, such as Python 3 or a browser script.
- Ask for one function. A second request can add the next piece.
- Do not paste secrets, tokens, or production connection strings into the prompt.
- Treat the explanation as a guide. Run the code to see what it does.
Code generator questions
Can it write a Python function from a plain description?
Yes. Describe the behavior and choose Python, or leave the language on automatic. You get a code block and a short explanation of how to run it.
Which languages can I pick?
Python, JavaScript, TypeScript, Go, Rust, Java, C++, HTML, CSS, SQL, and Bash, or automatic. The explanation is in the page language, not necessarily in English.
Will it build a whole application?
Ask for a function or a small program. A full app with accounts, storage, and a UI does not fit one reply. Generate one piece, then the next.
Is the code safe to run?
Read it first, and run it on sample data. Do not point a generated script at secrets or production until you understand it. Requests for malware or credential theft are refused.
Why is there no code block?
The model sometimes answers without a fenced block. Try a more specific request: language, input, and output. The page says so when no block comes back.
How long can the description be?
Up to 4000 characters, and it should be at least a short phrase. A precise paragraph works better than a single verb.
