This tool transforms the input JavaScript data into a JSON string. For example, it can convert a JavaScript expression, a JSON object, a string with special characters, and a larger text with newlines into a compactly stringified JSON string. It works in the browser and uses the native JSON.stringify() function to get the job done. This function converts elementary values (strings, numbers, constants, booleans), objects, and arrays to a quoted string. It also finds all control characters in the data and replaces them with the special JSON escape symbols. For example, it replaces a horizontal tab with the "\t" escape sequence, line feed with "\n", backspace with "\b", and form feed with "\f". It also adds a backslash character in front of quotation marks and other backslashes and wraps the output in double quotes for convenient usage so that you can instantly paste it into your code. If you want to convert a JSON string back into JavaScript or JSON data, you can use our Unstringify JSON tool. Json-abulous!

In this example, we stringify a syntactically well-formatted JSON object containing student information into a JSON string. We call the JSON.stringify() function on the input data and it converts line breaks into "\n" escape sequences, quotes into "\"" escape sequences, and tabs into "\t" escape sequences. Additionally, the entire output is enclosed in double quotes so it can instantly be assigned to a variable.
In this example, we apply the JSON.stringify() function to a text quote by Pythagoras. The quote contains various reserved JSON characters and as a result, we get backslash-escaped quotation marks \" instead of simple quotation marks, backslash-escaped newlines \n instead of regular newlines, and backslash-escaped tabs \t instead of regular tabs.
This example converts a simple JS code containing a loop over an array into a JSON string. It replaces control characters and special characters with escape symbols and returns the code fragment as a single double-quoted string.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
