FindUtils offers free, browser-based converters for transforming JSON into CSV, YAML, and XML — and back again — with no signup and no data uploaded to servers. Paste your JSON into the JSON to CSV, JSON to YAML, or other converter tools on findutils.com and get the output instantly.
Not every system uses JSON. Databases expect CSV. Kubernetes uses YAML. Legacy systems need XML. JSON conversion tools bridge these formats, letting you work with any data structure without writing code.
Why Convert JSON to Other Formats
JSON to CSV — Import JSON data into Excel, Google Sheets, or SQL databases JSON to YAML — Configuration inputs such as Kubernetes manifests and Ansible playbooks JSON to XML — Legacy system integration, SOAP APIs JSON to SQL — Loading JSON into relational databases JSON to TypeScript — Generating type definitions for frontend code
JSON to CSV: When and How
CSV (Comma-Separated Values) is the universal format for spreadsheets and databases.
When to Use CSV
- ✓ Importing data into Excel/Google Sheets
- ✓ Bulk loading into SQL databases
- ✓ Sharing data with non-technical users
- ✓ Creating backups of tabular data
Converting JSON to CSV
JSON Input (array of objects):
[
{ "id": 1, "name": "John", "email": "john@example.com" },
{ "id": 2, "name": "Jane", "email": "jane@example.com" },
{ "id": 3, "name": "Bob", "email": "bob@example.com" }
]CSV Output:
id,name,email 1,John,john@example.com 2,Jane,jane@example.com 3,Bob,bob@example.com
The FindUtils JSON to CSV Converter treats the JSON array as rows, and each object's keys become column headers.
Handling Nested JSON
Nested JSON Input:
[
{
"id": 1,
"user": { "name": "John", "email": "john@example.com" },
"status": "active"
}
]Most converters flatten nested objects:
CSV Output:
id,user.name,user.email,status 1,John,john@example.com,active
Pro Tip: If your JSON is deeply nested, simplify it before converting to CSV. You can use the FindUtils JSON Formatter to inspect the structure first.
JSON to YAML: Differences and Use Cases
Kubernetes and Ansible commonly use YAML configuration. Terraform configuration uses HCL or its JSON representation; YAML is not its native configuration syntax. See HashiCorp's configuration syntax reference.
When to Use YAML
- ✓ Kubernetes manifests (deployments, services)
- ✓ Ansible playbooks
- ✓ Docker Compose configurations
- ✓ CI/CD pipelines (GitHub Actions, GitLab CI)
- ✓ Application config files
Key Differences from JSON
| Aspect | JSON | YAML |
|---|---|---|
| Syntax | Braces {} | Indentation |
| Quotes | Required | Optional |
| Comments | Not supported | Supported with # |
| Readability | Compact | Readable |
Converting JSON to YAML
JSON Input:
{
"apiVersion": "v1",
"kind": "Pod",
"metadata": {
"name": "my-pod",
"namespace": "default"
},
"spec": {
"containers": [
{
"name": "app",
"image": "nginx:latest",
"ports": [{ "containerPort": 80 }]
}
]
}
}YAML Output:
apiVersion: v1 kind: Pod metadata: name: my-pod namespace: default spec: containers: - name: app image: nginx:latest ports: - containerPort: 80
The YAML version is more readable and compact. Notice:
- No braces or quotes needed
- Indentation shows structure
- Same data, cleaner format
JSON to XML: Legacy System Integration
XML was the standard before JSON. Many legacy systems still expect XML.
When to Use XML
- ✓ SOAP web services
- ✓ Legacy enterprise systems
- ✓ EDI (Electronic Data Interchange)
- ✓ Some government/compliance systems
Converting JSON to XML
JSON Input:
{
"user": {
"id": 123,
"name": "John Doe",
"email": "john@example.com"
}
}XML Output:
<?xml version="1.0" encoding="UTF-8"?> <class="text-rose-400">user> <class="text-rose-400">id>123</class="text-rose-400">id> <class="text-rose-400">name>John Doe</class="text-rose-400">name> <class="text-rose-400">email>john@example.com</class="text-rose-400">email> </class="text-rose-400">user>
Note: JSON arrays in XML need special handling. Arrays become repeated elements:
JSON:
{
"users": [
{ "id": 1, "name": "John" },
{ "id": 2, "name": "Jane" }
]
}XML:
<class="text-rose-400">users> <class="text-rose-400">user> <class="text-rose-400">id>1</class="text-rose-400">id> <class="text-rose-400">name>John</class="text-rose-400">name> </class="text-rose-400">user> <class="text-rose-400">user> <class="text-rose-400">id>2</class="text-rose-400">id> <class="text-rose-400">name>Jane</class="text-rose-400">name> </class="text-rose-400">user> </class="text-rose-400">users>
Tools Available for Conversion on FindUtils
JSON to CSV: Use the FindUtils JSON to CSV Converter to convert array data to spreadsheets
JSON to YAML: Use the FindUtils JSON to YAML Converter for configuration files
JSON to Other Formats: Try the JSON to XML Converter for legacy system integration
Check the data handling of the specific conversion tool and feature you use. A local-file conversion and a URL import can have different network behavior.
Choosing the Right Conversion Tool
| Format | Use Case | Our Tool |
|---|---|---|
| CSV | Spreadsheets, databases | JSON to CSV |
| YAML | Configuration, Kubernetes | JSON to YAML |
| XML | Legacy systems, SOAP | JSON to XML |
| SQL | Direct database loading | Use your database client |
Real-World Example: Kubernetes Deployment
You have JSON data describing a Kubernetes deployment:
{
"apiVersion": "apps/v1",
"kind": "Deployment",
"metadata": {
"name": "my-app",
"labels": { "app": "my-app" }
},
"spec": {
"replicas": 3,
"template": {
"spec": {
"containers": [
{
"name": "web",
"image": "my-app:1.0",
"ports": [{ "containerPort": 8080 }]
}
]
}
}
}
}Convert to YAML for Kubernetes:
apiVersion: apps/v1 kind: Deployment metadata: name: my-app labels: app: my-app spec: replicas: 3 template: spec: containers: - name: web image: my-app:1.0 ports: - containerPort: 8080
Now you can use kubectl apply -f deployment.yaml.
JSON Conversion Tool Comparison
| Capability | FindUtils |
|---|---|
| JSON to CSV | Yes |
| JSON to YAML | Yes |
| JSON to XML | Yes |
| CSV to JSON | Yes |
| Client-Side Processing | Yes |
| No Signup Required | Yes |
| Nested JSON Flattening | Yes |
Check the output type by type after a conversion. CSV cannot represent a nested object without a flattening or serialization rule. XML also needs an element naming rule. Keep the source JSON so you can compare values after export.
FAQ
Q1: Will my data be exactly the same after conversion? A: Almost always, but some conversions lose information:
- JSON comments (if any) are lost in XML/YAML conversion
- XML attributes become elements in JSON
- YAML comments are not preserved in JSON
Q2: Is it safe to paste sensitive data? A: Use example input in JSON to CSV. Check the output before you share it or use it in another application.
Q3: Can I convert very large files?
A: Most online tools handle files up to 10-50MB. For larger files, use CLI tools (jq, yq, xml2json) instead.
Q4: What about reverse conversion (CSV to JSON)? A: Use our CSV to JSON Converter to convert spreadsheets back to JSON format.
Q5: How do I convert JSON to SQL INSERT statements? A: Most JSON-to-SQL tools generate INSERT statements from JSON. Use your database client or a specialized SQL builder tool.
