Yes. Convert your JSON to CSV first using this tool, then open Excel, go to File → Import (Mac) or Data → From Text/CSV (Windows), and select your downloaded .csv file. Excel will parse the columns automatically. This is the most reliable way to get JSON data into an Excel spreadsheet.

Question 3

What is CSV format?

Accepted Answer

CSV (Comma-Separated Values) is a plain-text format for tabular data where each line represents a row and values within a row are separated by a delimiter (usually a comma). The first line typically contains column headers. CSV is widely supported by spreadsheet applications, databases, and data analysis tools.

Question 4

How do I handle nested JSON when converting to CSV?

Accepted Answer

This tool flattens nested JSON objects using dot notation. For example, a nested field like { address: { city: 'Seoul' } } becomes a column named 'address.city'. Deeply nested structures and arrays within objects are handled by serializing them as JSON strings in the cell.

Question 5

Accepted Answer

This tool supports bidirectional conversion. Switch to the CSV→JSON direction, paste your CSV data (with headers in the first row), and click Convert. The tool parses each row into a JSON object using the header names as keys, outputting a JSON array you can copy or use directly.
