User Guide: Converting JSON to CSV Table Rows

What is JSON to CSV Conversion?

JSON is an nested, hierarchical data structure excellent for application state APIs, whereas spreadsheet databases like Microsoft Excel or Google Sheets require tabular, flat rows of records. Converting JSON arrays to CSV maps each object key to a CSV column header, generating a clean rows-and-columns data model.

Step-by-Step Instructions

  1. Enter JSON: Paste your JSON array (or single configuration object) into the input workspace.
  2. Configure Options: Pick a delimiter (comma, semicolon, tab), enable flattening for multi-level child objects, and select whether to output header rows.
  3. Convert & Download: The conversion runs instantly. Copy the CSV output directly or download it as a spreadsheet-ready file.

Intelligent Nesting Flattening

Simple tools often break when converting nested parameters (like "address": {"city": "Boston"}), returning output placeholders like [object Object]. Our tool recursively flattens structures using dot notation (producing address.city as a dedicated column), ensuring data preservation.

Before & After Conversion Example

Structured Nested Input:
[
  {
    "id": 1,
    "user": { "name": "Sarah" }
  }
]
Tabular CSV Output:
id,user.name
1,Sarah
