Why use A → B → C?

A pipeline feeds each result directly into the next compatible converter. Use one when the destination needs an intermediate representation or when you want to inspect and normalize that middle format.

  • JSON → CSV → XLSX turns records into rows before building a workbook.
  • Markdown → HTML → DOCX resolves markup before creating a document.
  • SVG → PNG → PDF intentionally flattens vector artwork before placing it on a page.
Only type-compatible next steps are offered. Lossy steps are marked before you run them.

How to convert FITS to FITS metadata JSON

Before you start

Drop one or more FITS files; this format cannot be pasted as plain text.

Accepted: .fits, .fit, .fts · application/fits
  1. Choose or drag one or more FITS files onto the drop zone.
  2. Confirm the detected format. Mixed-format batches are flagged before conversion.
  3. Select “Convert on this device.” Produces previewable FITS metadata JSON text and a correctly named download.

How this converter behaves

Biological, molecular, genomic, matrix, and binary scientific metadata are parsed into bounded typed records and serialized locally without executing content.

What happens to your data?

The conversion engine runs in this browser tab. OmniCastConverter has no upload API and never sends your content, file name, or converted result to a server.

Fidelity and limitations

This route is classified as structural. The converter preserves meaning and structure supported by both formats.

  • Scientific records are validated and normalized, but domain-specific annotations and application conventions may require expert review.
