Syntaxerror Unexpected Token O In Json At Position 1
However, working with JSON can sometimes lead to errors, especially when dealing with syntax errors. A common syntax error is the “SyntaxError: Unexpected token” error. This error occurs when there is an unexpected character or symbol in the JSON syntax.
Determining the Cause of a SyntaxError
When encountering a syntax error in JSON, it is crucial to understand its cause. Syntax errors can be caused by various factors, such as missing or extra characters, incorrect placement of commas or colons, or invalid values for keys or values.
To determine the cause of the syntax error, it is important to carefully examine the JSON code and identify any discrepancies. It is helpful to use a JSON validator or linter, such as JSONLint or online editors that provide syntax highlighting and error checking, to quickly identify and fix issues in the JSON code.
Handling Unexpected Tokens in JSON
One specific type of syntax error that can occur in JSON is an “Unexpected token” error. This error typically indicates that an unexpected character or symbol was encountered at a specific position in the JSON code. The error message includes the token that was unexpected and its position within the JSON code.
Dealing with a SyntaxError Unexpected Token ‘o’
One variant of the “Unexpected token” error is the “SyntaxError: Unexpected token o in JSON at position 1” error. This error message signifies that an unexpected ‘o’ character was found at position 1 in the JSON code.
This particular error commonly occurs when attempting to parse JSON data without properly enclosing it in double quotes. JSON requires all strings, including object keys and string values, to be enclosed in double quotes. Failure to do so results in a syntax error, with the error message pointing to the first character of the unquoted value, which is often ‘o’.
Identifying the Position of the SyntaxError in JSON
The error message for a syntax error in JSON also provides the position where the error occurred. This position represents the index of the character in the JSON code that caused the error.
By knowing the position of the syntax error, developers can quickly locate and fix the issue. Most text editors and IDEs display line and column numbers, which can aid in pinpointing the exact location of the error in large JSON files.
Solving the SyntaxError Unexpected Token ‘o’
To solve the “SyntaxError: Unexpected token o in JSON at position 1” error, it is necessary to ensure that all strings in the JSON code are enclosed in double quotes. This includes object keys, string values, and any other place where a string is expected.
For example, the following JSON code would result in a syntax error:
To fix the error, the object’s keys should be enclosed in double quotes, like this:
Remember to double-check the entire JSON code for any missing or misplaced double quotes.

Syntaxerror: Unexpected Token In Json At Position 1
Causes of SyntaxError: Unexpected token in JSON at position 1
1. Missing or extra brackets or braces:
One possible cause of this error is missing or extra brackets or braces in your JSON data. JSON requires proper syntax with opening and closing brackets or braces to define the beginning and end of an object or array. For example, if you have a missing closing bracket, the parser will encounter an unexpected token at position 1 and throw the error.
2. Invalid data types:
JSON supports a limited set of data types, including strings, numbers, booleans, null, arrays, and objects. If your JSON data contains an unexpected data type, such as function, undefined, or a custom object, it can trigger the syntax error.
3. JSON string formatting:
Another common cause is incorrect formatting of JSON strings. JSON strings must be enclosed in double quotes, and any double quote within the string should be escaped with a backslash (\”) to avoid conflicts. Failure to follow these string formatting rules can result in a syntax error.
4. Encoding issues:
Encoding issues can also cause unexpected token errors. If your JSON data is not encoded properly, especially with non-ASCII characters, it can result in an error. Ensure that you are using a compatible encoding such as UTF-8 for your JSON data.
Solutions to fix SyntaxError: Unexpected token in JSON at position 1
1. Validate your JSON:
The first step in fixing this error is to validate your JSON data. You can use online JSON validators or built-in methods available in programming languages to check the syntax and structure of your JSON. These tools will highlight any errors or inconsistencies in your JSON data.
2. Check for missing or extra brackets or braces:
Review your JSON data carefully, focusing on the placement and pairing of brackets and braces. Make sure that every opening brace or bracket has a corresponding closing brace or bracket. Adding or removing the necessary brackets or braces can resolve the issue.
3. Verify data types:
Ensure that the data types used in your JSON comply with the JSON specification. Remove any invalid or unexpected data types from your JSON data, such as functions or undefined values. Convert them to supported data types or remove them altogether.
4. Validate JSON string formatting:
Double-check the formatting of your JSON strings. Ensure that all strings are enclosed in double quotes, and any double quote within the string is correctly escaped with a backslash (\”). Correct any formatting errors in your JSON strings.
5. Resolve encoding issues:
If you suspect encoding issues, try using a compatible encoding like UTF-8 for your JSON data. Ensure that both the source and the parser are using the same encoding. You can also try converting your data to a different encoding if needed.
