JSON and CSV appear in APIs, spreadsheets, exports, configuration files and small automation jobs. Moving between them is common, but a conversion can go wrong when headers, quotes, arrays or nested values are misunderstood.
The gioyous.it Tools collection includes several small utilities for inspecting and converting structured data directly in the browser.
Start by validating the JSON
Before converting data, check that the JSON is valid and understand whether its top level is an object or an array. The JSON Workbench formats and validates JSON, making missing commas, mismatched brackets and other syntax mistakes easier to spot.
Convert CSV to JSON
The CSV to JSON utility turns tabular rows into JSON objects using the header row as property names. For a quick structural check before conversion, use the CSV Inspector to count rows and columns, inspect quoted fields and identify rows with inconsistent widths.
Convert JSON arrays to CSV
The JSON Array to CSV tool converts arrays of objects into comma-separated output. CSV fields may need quoting when they contain commas, quotation marks or line breaks, so inspect the result before importing it into another system.
Find a value inside nested JSON
When a document contains nested objects and arrays, JSON Pointer Explorer resolves a path such as /users/0/name using RFC 6901 pointer rules. If you need to turn arbitrary text into a JSON string literal, JSON String Escaper handles the escaping step.
Keep the workflow small
These utilities are designed for focused tasks rather than replacing a full data pipeline. Most process input locally in your browser; check each tool’s description before using sensitive material or relying on a network-dependent feature.
