Python Dictionary to JSON Converter

How to Use

  1. Enter a Python Dictionary: Type or paste a valid Python dictionary into the input textarea. For example: {"name": "John", "age": 30, "address": {"city": "Delhi", "pin": 110001}}. Nested dictionaries are supported.
  2. Choose Output Format: Click "Convert to Formatted JSON" for a pretty-printed JSON with indentation, or "Convert to Minified JSON" for a compact version without spaces.
  3. View the Result: The converted JSON will appear in the output textarea below. If an error occurs, the input text will be shown with the problematic line highlighted in red, along with the exact line and column of the error.
  4. Copy the Output: Click "Copy Output" to copy the JSON (or error text) to your clipboard for use elsewhere.
  5. Clear Fields: Click "Clear" to reset both the input and output fields.
  6. Check for Errors: If the input is invalid, an error message will appear below the output textarea, and the problematic line will be highlighted with the line and column numbers indicated.

Frequently Asked Questions

What is this tool?

This tool converts a Python dictionary (entered as text) into JSON format. It supports both formatted (pretty-printed) and minified JSON output, with features like copying to clipboard, clearing the input, and highlighting error lines with line and column numbers.

What kind of input is supported?

You can enter any valid Python dictionary, including nested dictionaries. For example: {"key": "value", "nested": {"a": 1}}. The tool automatically converts Python-specific syntax (like True, False, None, single quotes) to JSON-compatible syntax.

Why am I seeing an error message?

An error message appears if the input is not a valid Python dictionary. Common issues include missing quotes around strings, trailing commas, or incorrect syntax. The problematic line will be highlighted in the output textarea, with the exact line and column numbers shown to help you fix it.

What happens if I enter invalid input?

If the input is invalid, the output textarea will show the input text with the problematic line highlighted in red, along with a note indicating the line and column of the error (e.g., "Error at line 68, column 11"). An error message will also appear below, explaining the issue. Fix the input and try again.

Does this tool support large dictionaries?

Yes, the tool can handle large and complex nested dictionaries, as long as they are valid. However, very large inputs may slow down the conversion slightly due to browser processing limits.
