Rule in plain English

Write a prompt specifying the conversion details: delimiter, array handling (concatenate or explode into rows), columns to include or exclude, and encoding preferences.

THE SOLUTION

Smart mapping

Orchestria analyzes your JSON and generates a consistent CSV through intelligent mapping.

Recursive flattening : nested objects converted to columns (address.street)
Array handling : concatenation, row explosion or serialization
Consistent columns : same number of fields on every row
Configurable delimiter : comma, semicolon or tab for your target tool
Adaptive encoding : UTF-8 with BOM for Excel, standard for databases

Describe the desired output and Orchestria generates the right conversion flow.

Why convert JSON to CSV?

Modern APIs return JSON, but many business tools still rely on tabular files.

Excel and Google Sheets : pivot tables, charts and filters need flat tabular data
Power BI and Tableau : structured columnar data for dashboards and reports
Database imports : bulk loading into MySQL, PostgreSQL or SQL Server
ERP and accounting : many legacy systems only accept CSV

Orchestria transforms your API responses into clean CSV without writing code.

Flattening nested structures

JSON is hierarchical — flattening it into CSV columns presents several challenges.

Nested objects : {"address": {"street": "..."}} must become address.street
Arrays : how to represent ["urgent", "client"] in a single cell?
Missing values : some records have fields that others lack entirely
Variable depth : data nested across multiple unpredictable levels
Mixed types : a field may contain a number, a string or an object

Custom scripts quickly become unmanageable when the JSON structure evolves.

HOW IT WORKS

How it works

Provide input and output samples

Paste a sample of your JSON data as input, and provide the expected CSV structure as output. This tells Orchestria exactly how to flatten your data.

Describe the transformation

Write a prompt specifying the conversion details: delimiter, array handling (concatenate or explode into rows), columns to include or exclude, and encoding preferences.

Execute and reuse via API

Orchestria generates a workflow that performs the conversion. Run it instantly and reuse it via API for all your future JSON-to-CSV transformations.

The Excel equivalent

Traditional method

In Excel, you would need to use Power Query to import JSON, manually configure column expansion for nested objects, and handle type errors. Every structure change requires rebuilding the query from scratch.

With Orchestria

With Orchestria, paste your JSON and get a perfectly flattened CSV in seconds. Nested objects are automatically converted to columns, and arrays are handled according to your preference.
