Output naming & batch behavior

Filename templateAvailable variables: {output} (converter’s meaningful name), {name}, {target}, {ext}, {index}. Duplicate names receive a safe numeric suffix.

Pipeline 1 linear · 0 branches

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.

About this conversion

How to convert Coordinate CSV to GeoJSON

Before you start

Paste valid Coordinate CSV syntax or drop one or more .coordinates.csv files.

Accepted: .coordinates.csv · text/csv

Paste valid Coordinate CSV content, choose files, or drag them onto the drop zone.
Confirm the detected format. Mixed-format batches are flagged before conversion.
Select “Convert on this device.” Produces previewable GeoJSON text and a correctly named download.

How this converter behaves

The source records are parsed into a small, typed interchange model and serialized into the destination format with explicit fidelity limits.

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.

This interoperable route supports point features only and uses WGS84 longitude/latitude coordinates; it does not transform coordinate reference systems.
