Converters

Every CSV converter, in one place.

Convert CSV to (and from) almost any format — all in your browser, with smart type detection so numbers, dates and booleans survive the round trip. Pick a format below.

Data formats

CSV ↔ JSON, SQL, YAML, XML and friends.

Structured data formats, both directions. Types are inferred from your data, not stringified.

Spreadsheets & columnar

Excel, Arrow and Parquet.

Typed workbooks and the columnar formats pandas, polars and DuckDB read — written entirely in the browser.

Docs & markup

Drop a table into your docs.

GitHub-flavored Markdown, semantic HTML, LaTeX, reStructuredText, AsciiDoc, MediaWiki and PDF.

Geospatial

Map formats from lat/lng columns.

Turn coordinate columns into GeoJSON, KML or GPX — and back.

Other

Fixed-width, code, and app imports.

Re-delimit, generate code, or format for Notion and Airtable.

FAQ

Common questions.

  • ·

    Are all these converters free?

    Yes — every converter runs in your browser, free, no signup and no required upload. Heavy engines (Excel, Arrow, Parquet) load on demand the first time you use them.

  • ·

    Do conversions preserve column types?

    Yes. We infer a type per column from your data, so numbers stay numbers, dates stay dates and booleans stay booleans rather than becoming quoted strings.

  • ·

    Which direction is supported?

    Most tabular formats convert both ways (CSV→X and X→CSV). Each card above is a separate tool; pick the direction you need.
