Frequently Asked Questions

Common questions about converting data formats online.

Which data formats are supported?

MorphFlux supports JSON, CSV, XML, YAML, TOML, TSV, Excel (XLSX/XLS), and SQL output. You can convert between any supported combination.

Can I paste data directly instead of uploading a file?

Yes. Switch to Text mode to paste JSON, CSV, XML, YAML, or any other text format directly. The converter auto-detects the input format.

Is my data sent to a server?

No. All data conversions run entirely in your browser. Your data never leaves your device, making MorphFlux safe for sensitive or proprietary data.

Does it handle nested JSON objects?

Yes. Nested JSON objects are automatically flattened using dot notation when converting to CSV. For example, user.name becomes a column header in the CSV output.

Is there a file size limit?

Data files up to 50MB are supported. Since conversion happens in your browser, very large files may take a moment to process.

Can I convert Excel files to JSON or CSV?

Yes. Upload an XLSX or XLS file and select JSON, CSV, XML, or TXT as the output format. The first sheet is converted by default.

How does auto-detection work for pasted text?

The converter analyzes the first few characters and lines of your pasted text to detect JSON, CSV, XML, YAML, and other formats automatically. You can always override the detected format manually.

Can I generate SQL from CSV or JSON?

Yes. Select SQL as the output format when converting CSV or JSON to generate ready-to-use SQL INSERT statements for database import.
