How to convert CSV to HTML

  1. Add your CSV files

    Drag one or more CSV files onto the dashed area, or tap it to pick them from your device.

  2. Choose HTML and the options

    HTML is already selected; the options hold the settings that matter for this conversion.

  3. Convert and download

    Press “Convert to HTML”. When it’s done, download the files one by one or all together in a ZIP archive.

Good to know. Tables with many columns are laid out in landscape.

Questions about CSV and HTML

What happens to multiple sheets?

Formats with several sheets (XLSX, ODS, HTML, PDF) keep them all; CSV and TSV hold only one: in the options you can choose to convert the first sheet or create one file per sheet.

Are my CSV files uploaded to a server?

No. The conversion from CSV to HTML happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.

How many files can I convert at once?

Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.

Does it work on iPhone and Android?

Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.

Do I need an internet connection?

Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
