About Comma-Separated Values
Common Use Cases
- Opening YAML config data in Excel
- Extracting tabular data from YAML files
- Reporting on Ansible and Kubernetes data
YAML is great for configuration and structured data, but spreadsheets are where analysis happens. Converting YAML to CSV flattens nested mappings into columns and sequences into rows, producing output that opens cleanly in Excel, Google Sheets, and every data analysis tool.
YAML supports nested mappings, sequences, and typed values. CSV is a flat grid of text cells, so conversion involves flattening hierarchical YAML data into rows and columns.
Why Convert YAML to CSV?
Analyze config data in spreadsheets
Open YAML configuration data, Ansible inventories, and Kubernetes resource lists in Excel or Google Sheets for sorting, filtering, and reporting.
Extract data for business stakeholders
Technical teams store data in YAML, but business users need spreadsheets. CSV bridges the gap between DevOps data and business analysis.
Import into SQL databases
PostgreSQL, MySQL, and data warehouses all have CSV import tools. Converting YAML to CSV is a quick path to get structured data into relational databases.
Flatten nested data for reporting
Nested YAML keys are flattened to dot-notation columns, turning hierarchical config data into a flat table you can pivot and chart.
When to use each
Use YAML when...
- Storing configuration and infrastructure data
- Human-readable nested structures
- DevOps tools that read YAML natively
- Version-controlled config files
- Typed values (strings, numbers, booleans)
Use CSV when...
- Opening data in Excel or Google Sheets
- Importing into SQL and BI tools
- Sharing with non-technical stakeholders
- Flat tabular analysis and reporting
- Universal spreadsheet compatibility
Common use cases
- Opening YAML config data in Excel
- Extracting tabular data from YAML files
- Reporting on Ansible and Kubernetes data
How to use
- Upload your YAML file. Drag and drop a .yaml or .yml file onto the upload area, or click to browse. Files up to 500 MB are supported.
- Start the conversion. Click Convert File. YAML mappings are flattened to columns, sequences become rows, and nested keys use dot notation.
- Download your CSV. Save the .csv file and open it in Excel, Google Sheets, or import into your database. Files are deleted from our servers within 1 hour.
Frequently asked questions
- How are nested YAML keys handled?
- Nested keys are flattened into dot-notation column headers. A key like server.port becomes a column named server.port in the CSV.
- What about YAML sequences?
- Sequences of mappings become CSV rows. Each mapping in the sequence produces one row, with the keys as column headers.
- Are YAML data types preserved?
- CSV has no type system, so all values are written as text. Numbers and booleans appear in their string representation and most spreadsheet tools re-infer the types.
- Does it handle multi-document YAML?
- The converter processes the first document in a multi-document YAML file. Split your file if you need to convert multiple documents.
- What encoding is used?
- The output is UTF-8 encoded, preserving accented characters, emoji, and non-Latin scripts.
- Is converting YAML to CSV free?
- Yes. Free with no signup. Anonymous users get a daily allowance, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
- What is the file size limit?
- The maximum file size is 500 MB per conversion.
