How to Convert JSON to Excel, CSV, XML, and YAML — Free Online Guide

JSON is the default format for API responses, config files, and export buttons — but it's rarely the format the next person in line actually wants. A manager wants a spreadsheet. A legacy integration wants XML. A build tool wants YAML. Converting between them by hand is tedious and easy to get wrong, especially with nested data.

Why JSON conversion comes up so often

Most modern systems produce JSON because it's easy for code to generate and parse. But the people and systems downstream of that code often aren't reading JSON directly — an operations team wants to filter results in Excel, a data import script expects CSV rows, and older enterprise systems still speak XML almost exclusively.

JSON to Excel, for reports and review

When someone needs to review, sort, or share API output without touching code, a spreadsheet is the fastest path. The JSON ⇄ Excel Converter takes a JSON array of objects and turns each object into a row, with keys becoming column headers — useful for turning a support ticket export or a product catalog dump into something a non-technical teammate can open directly.

JSON to CSV, for imports and scripts

CSV is the lowest-common-denominator format almost every tool accepts — CRMs, spreadsheet imports, database bulk loaders. The JSON ⇄ CSV Converter handles the same row-per-object conversion but outputs plain comma-separated values, which is often what an import wizard is actually asking for when a JSON upload gets rejected.

JSON and XML, for legacy systems

Plenty of enterprise APIs, SOAP services, and older data pipelines still run on XML. Rather than hand-writing XML tags around every field, the XML ⇄ JSON Converter converts a JSON object into well-formed XML (or the reverse, when you've received an XML payload and need to work with it as JSON in code). This is especially useful when integrating a modern JSON-based app with an older system that has no plans to change.

JSON and YAML, for configuration

YAML has become the standard for configuration files — Docker Compose, Kubernetes manifests, CI pipelines. But writing YAML by hand for a large or deeply nested config is error-prone, since indentation carries meaning. If you already have the structure as JSON, the YAML ⇄ JSON Converter converts it to clean YAML instantly, and can convert an existing YAML config back to JSON when you need to process it programmatically.

A few real scenarios

1. A developer pulling a JSON API response and needing to hand a filtered subset to a non-technical stakeholder as a spreadsheet.
2. An analyst who received a JSON export from an analytics tool and needs it in CSV for a BI tool that only accepts CSV uploads.
3. An engineer configuring a Kubernetes deployment who has the values as JSON from a script and needs valid YAML to commit.
4. A team integrating with a partner's legacy XML API while their own internal services are entirely JSON-based.

Everything stays in your browser

All four converters run entirely client-side — your JSON, CSV, XML, or YAML data is processed in the browser and never uploaded to a server, which matters when the data includes anything sensitive like customer records or internal configuration.

Start with the JSON ⇄ Excel Converter for spreadsheet output, or jump straight to JSON ⇄ CSV, XML ⇄ JSON, or YAML ⇄ JSON depending on the format you need.
