How to use Convert JSON to CSV
- 1. Paste your JSON array. Paste a JSON array of objects, such as a list of users or products. Every distinct key across the objects becomes a column, even if some records leave it blank.
- 2. Toggle the header row. Turn on Header row to write column names on the first line, which spreadsheet apps and CSV importers usually expect. Leave it off if the destination file already supplies its own headers.
- 3. Copy the CSV output. Copy the comma-separated result and paste it into Excel, Google Sheets or any tool that accepts CSV, or save it as a .csv file for a bulk import.
When to use Convert JSON to CSV
Convert JSON to CSV is for turning an array of JSON records into a spreadsheet-ready table. APIs and export tools frequently return arrays of objects, and CSV remains the format most spreadsheet software, BI tools and bulk import forms expect instead.
- Exporting API results for a spreadsheet report. You pulled a JSON array of sales records from an internal API and a colleague needs the same data as a CSV file to build a pivot table in Excel.
- Preparing a bulk import for an e-commerce platform. A platform like Shopify or WooCommerce expects product data as CSV, but your source system, a headless CMS or custom database, only exports JSON.
- Feeding data into a BI or analytics tool. A business intelligence tool imports CSV files for dashboards, and the data you have access to comes from a JSON API endpoint.
- Sharing a dataset with a non-technical teammate. Someone on the team who is comfortable in spreadsheets but not JSON needs to review a dataset you only have as a JSON array from a script's output.
