What is JSON to CSV conversion?

JSON to CSV conversion is the process of transforming data from JavaScript Object Notation (JSON) format to Comma-Separated Values (CSV) format. This makes complex JSON data readable in spreadsheet applications like Excel.

How do I use this converter?

Simply paste your JSON data or upload a JSON file, configure your preferred CSV options (like delimiters and quote style), and click convert. The tool will generate a CSV file ready for download.

What types of JSON can I convert?

Our tool handles various JSON structures including simple key-value pairs, nested objects, arrays, and complex hierarchical data. It automatically flattens nested structures into a tabular format.

Is there a size limit for conversion?

While the tool can handle large files, we recommend keeping files under 10MB for optimal browser performance. For larger files, consider using our batch processing feature.

How are nested objects handled?

Nested objects are flattened using dot notation (e.g., 'user.address.city'). You can customize the separator and choose different flattening strategies through the options panel.

What happens to arrays in JSON?

Arrays can be handled in multiple ways: expanded into separate rows, joined into a single cell with a custom delimiter, or processed as individual columns. You can choose the preferred method in the settings.

How are null values handled?

By default, null values are converted to empty cells in CSV. You can customize this behavior to use specific placeholder values like 'NULL', 'N/A', or any custom text.

What about special characters?

Special characters are properly escaped according to CSV standards. You can choose different escaping strategies and quote styles to handle special characters in your data.

Can I change the delimiter?

Yes, you can choose different delimiters including comma, tab, semicolon, or any custom character. This is useful when your data contains commas or when working with different regional formats.

How do I handle quotes in the data?

The converter automatically handles quotes by escaping them. You can choose between different quote styles (single, double, or none) and escaping strategies in the options panel.

Can I customize the header row?

Yes, you can customize column headers, reorder them, exclude certain columns, or use custom names. You can also choose to exclude the header row entirely.

What encoding options are available?

The tool supports various encodings including UTF-8, UTF-16, and ASCII. You can select the appropriate encoding based on your data and requirements.

Why isn't my JSON parsing correctly?

Common issues include invalid JSON format, missing brackets or commas, and incorrect quotation marks. The tool provides detailed error messages to help identify and fix parsing problems.

How do I fix column misalignment?

Column misalignment usually occurs with inconsistent data structures. Use the 'Normalize Data' option to ensure consistent columns across all rows, or adjust the flattening settings.

What if my CSV is too large to open?

For large files, use the 'Stream Processing' option or split the conversion into smaller chunks. You can also enable compression to reduce the file size.

How do I preserve data types?

Enable the 'Preserve Data Types' option to maintain number and boolean types. You can also use the 'Type Formatting' settings to customize how different data types are represented in the CSV.

Interesting History

Origins of CSV

CSV format dates back to the early days of computing in the 1960s. IBM's Fortran programming language used comma-separated values for data storage, making it one of the earliest standardized data exchange formats.

JSON Evolution

JSON was created by Douglas Crockford in the early 2000s while working at Yahoo!. It emerged as a lightweight alternative to XML and quickly became the preferred format for web APIs and data interchange.

Data Transformation

The need to convert between JSON and CSV grew with the rise of web services and data analysis tools. Spreadsheet programs like Excel popularized CSV, while web APIs standardized on JSON, creating a need for reliable conversion tools.
