How CSV form import works

You can upload a CSV to build or replace your form’s fields at any time. Click Download template to get a starter file. Edit it in your spreadsheet of choice (Excel, Numbers, Google Sheets, LibreOffice — any of them, as long as you save as comma-separated CSV). Then click Upload CSV and pick the saved file. Your form is rebuilt in one shot.

Uploading replaces all existing fields. This makes corrections easy: upload, review the result in the builder, adjust your CSV, and upload again.

Columns

The CSV has 27 columns, in this order:

  • Field — the field type. One of: text, email, phone, number, textarea, dropdown, checkbox, radio, date, divider, subtitle, description.
  • Label — the question prompt the respondent sees (in English). Required for all field types except divider. For subtitle and description, this is the heading or paragraph text.
  • FieldName — the JSON key your data will be stored under (e.g., email_address). Optional. If you leave it blank, we’ll auto-fill question1, question2, etc. We’ll lowercase, replace spaces and special characters with underscores, and rename duplicates by adding _2, _3, etc.
  • Required — true, false, yes, no, y, n, 1, 0, or blank (treated as false). Ignored for non-input fields.
  • Placeholder — optional hint text shown inside the input. Only applies to single-line, multi-line, number, and date fields. Ignored for choice fields, dividers, subtitles, and descriptions.
  • FrenchLabel — the French version of Label. Leave blank to keep the field English-only.
  • FrenchPlaceholder — French version of Placeholder.
  • Option1–Option10 — choices for dropdown, checkbox, radio, and ranking fields. At least one is required for choice fields; ranking requires at least two. You don’t need to fill every slot — if Option7–Option10 are blank, only the first 6 are created. Empty options between filled ones are skipped (Option1=Yes, Option2=, Option3=No becomes the choices [Yes, No]).
  • FrenchOption1–FrenchOption10 — French versions of the options, paired by index. Leave a slot blank to keep that option English-only.

Field types

  • text — single-line input.
  • email — email-validated input.
  • phone — telephone-formatted input.
  • number — numeric input.
  • textarea — multi-line input.
  • dropdown — single-select from a list.
  • checkbox — multi-select from a list.
  • radio — single-select displayed as radio buttons.
  • ranking — drag-and-drop priority ranking. Uses the same Option1–Option10 columns as choice fields. Requires at least 2 options.
  • rating — a rating scale from 1 to 5. Change the range and add end labels in the builder after importing.
  • slider — a number picked on a slider from 0 to 100. Change the range and step in the builder after importing.
  • date — date picker.
  • divider — a horizontal line. Only the Field column matters.
  • subtitle — section heading. The Label column is the heading text. FrenchLabel provides the French version.
  • description — paragraph of explanatory text. Same column rules as subtitle.

Common questions

I have more than 10 options for a dropdown. Import what fits in Option1–Option10, then add the rest in the builder.

Excel saved my file with semicolons instead of commas. Some French Excel locales default to semicolon-separated CSV. Use File → Save As → CSV (Comma delimited) to force commas.

My French translation is missing for one option. That’s fine — leave the FrenchOption slot blank. The option will be displayed in English on the live form for both languages.

I uploaded the wrong file / I want to change the form. Just upload the corrected CSV again — each upload replaces all fields.

Generating the fields with an AI assistant

Instead of filling a spreadsheet, you can have an AI assistant draft the form for you. Stelld never sends your text anywhere: you copy a prompt we prepare, run it in the assistant you already use, and paste the reply back.

  1. On a new form, click Generate with AI, paste your notes (the text of an old form, an email, bullet points) and click Copy prompt.
  2. Paste the prompt into ChatGPT, Claude, Copilot or any other assistant and send it.
  3. Copy the assistant’s whole reply, paste it under Paste the answer, and click Create form.

Review before you publish. Assistants occasionally invent a question or reorder options. The text you paste into your assistant is handled under that service’s privacy terms, not Stelld’s.

The JSON the assistant returns

  "title": "Fall registration",
  "description": "Sign your child up for the fall session.",
