JSON All-in-One guides

Get from JSON to the next step

Open a file, find the records you need, or turn an API response into something your project can use. Pick a task below. Each guide includes examples you can read and adapt.

Open and inspect

Read files, compare changes, and keep track of the values that matter.

Practical guide

Open large JSON files in Chrome

A practical local workflow for inspecting large JSON files in Chrome while choosing operations that fit the data shape.

Practical guide

How to open a JSON file

Open a JSON file in a text editor, Chrome, or a structured viewer, and troubleshoot local file access when Chrome shows raw text.

Practical guide

Find invisible characters in JSON

Detect zero-width, bidirectional, and control characters in JSON, inspect their code points, and confirm the security findings before the data moves downstream.

Query and shape

Select the right records, transform them, and build a starting schema.

Code for your stack

Turn sample data into models, then review the details for your language.

Start here

Generate code from JSON

Choose a JSON-to-code target, understand what sample-derived models can prove, and move from one JSON shape into TypeScript, Python, Java, Kotlin, C#, Go, or Rust.

Practical guide

Generate TypeScript types from JSON

Turn a representative JSON response into TypeScript interfaces or classes, then review optional fields, nulls, arrays, dates, and numeric policy before using the types.

Practical guide

Generate Python dataclasses from JSON

Create Python 3 dataclass models from a JSON sample, then add the explicit loading and coercion code your application actually needs.

Practical guide

Generate Kotlin data classes from JSON

Generate Kotlin data classes or classes from a JSON sample, then review nullability, naming, package layout, and serializer work that remains manual.

Practical guide

Generate C# models from JSON

Generate C# classes or records from JSON, then review nullable reference types, property names, numeric policy, and .NET deserialization glue.

Practical guide

Generate Go structs from JSON

Generate Go structs with JSON tags from a sample, then review exported names, pointers, numeric policy, package layout, and decoding behavior.

Practical guide

Generate Rust structs from JSON

Generate Rust structs from JSON, compare plain and Serde output, and verify Cargo dependencies, Option semantics, and deserialization separately.

Export your way

Choose a format and prepare data for spreadsheets, configuration, or documentation.

Start here

Choose a JSON export format

Compare CSV, TSV, YAML, TOML, XML, .properties, Markdown, HTML table, and NDJSON exports from JSON before choosing the right guide.

Practical guide

Convert JSON to XML with a clear mapping

Convert JSON to XML locally and see what happens to the root, arrays, escaped text, invalid element names, nulls, and schema-specific expectations.

Practical guide

Convert nested JSON to .properties

Convert nested JSON to a .properties file, then check the flattened keys, array indexes, escaped values, and the rules of the receiving application.

Practical guide

Convert JSON to a Markdown table

Create Markdown tables from JSON arrays for READMEs, issues, and documentation while handling nested fields, pipes, and multiline cells.

Practical guide

Convert JSON to an HTML table

Export a JSON array as a readable HTML table report and review saved-artifact behavior, escaping, sorting, and mapping limits.
