Steps

How it works.

Each step names the feature as it appears in the product.

  1. Step 1

    File template

    Describe the workbook's layout as an Excel template: columns, types and the header row.

  2. Step 2

    Field mapping

    Choose and rename the columns you want, and add clean-up rules such as trim, case and date formats.

  3. Step 3

    Transform Data

    Run the file and download the result as CSV or TSV. Preview shows the first rows and every error by row and column.

  4. Step 4

    Quick Transform

    For a fast clean without a template: whitespace, duplicates, dates, phone numbers and lowercase emails.

  5. Step 5

    Export and Import

    Save your templates and mappings to one JSON file and bring them back on another browser.

Questions

Common questions.

Is my file uploaded anywhere?

No. The free edition reads files in your browser and nothing is uploaded. Nothing you enter is sent to ExtensibilityCo except what you ask for: signing in, the Upgrade and Roadmap pages, and feedback you send.

Can I reuse the setup next time?

Yes. Templates and mappings are saved in the browser, and Export and Import writes all of them to one JSON file that you can bring back on any machine.
