JSON/CSV Converter
UtiliStudio Workspace ToolTransform data between tabular JSON arrays and CSV documents. Supports customizable delimiters, nested property flattening, and automatic data type inference.
Key Capabilities
Bidirectional Tabular Conversion
Convert arrays of JSON objects into tabular CSV records and parse CSV spreadsheets back into structured JSON arrays.
Nested Object Flattening
Automatically flatten deep JSON hierarchies into dot-notated column names (like user.contact.email) for spreadsheet clarity.
Configurable Delimiters & Quotes
Choose standard comma (,), semicolon (;), or tab (\t) delimiters, with RFC 4180 compliant quote escaping for commas and newlines.
Automatic Type Inference
Convert CSV text to typed JSON values, automatically identifying numbers, booleans, and null fields rather than pure strings.
How to Use JSON/CSV Converter
Select conversion direction
Choose JSON to CSV for spreadsheet export or CSV to JSON for structured data ingestion.
Paste input data
Paste your JSON array or CSV document into the input pane.
Adjust delimiter and flattening
Select preferred column delimiters and enable nested property flattening if converting complex JSON.
Copy or export converted output
Copy the formatted output directly or download the file as a CSV spreadsheet or JSON document.
Practical Examples
Converting a JSON Array of User Objects to CSV
A list of user records converted into clean CSV rows with header columns.
[
{ "id": 1, "name": "Sarah Connor", "role": "Engineer", "active": true },
{ "id": 2, "name": "John Connor", "role": "Lead", "active": false }
]id,name,role,active
1,"Sarah Connor","Engineer",true
2,"John Connor","Lead",falseCommon Use Cases
Exporting API Data to Spreadsheets
Convert JSON API payloads into CSV format for analysis in Microsoft Excel, Google Sheets, or Apple Numbers.
Preparing Data for Database Ingestion
Transform CSV exports from third-party tools into JSON arrays ready for document databases like MongoDB or PostgreSQL JSONB columns.
Flattening Hierarchical Datasets
Turn complex nested JSON objects into normalized flat tables with dot-separated column headers.
Normalizing Mixed Delimiter Formats
Convert tab-separated values into standard comma-separated files or vice versa with clean quote escaping.
Frequently Asked Questions
How are nested JSON structures handled in CSV?
The flattener converts nested object keys into dot-separated column headers (such as address.city and address.zipcode) to represent hierarchies within flat tables.
Does CSV-to-JSON conversion preserve data types?
Yes. An integrated type detector automatically converts numeric strings to numbers and recognizes boolean values (true/false) and nulls.
What delimiters can I use?
You can select commas (,), semicolons (;), or tabs (\t) to format CSV or TSV output to match regional spreadsheet conventions.
