How to Fill Web Forms from Spreadsheet Data with AI

Dec 30, 2025·Updated Oct 6, 2026·6 min read

A lot of data entry starts in a spreadsheet. A row holds everything a form needs, name, email, company, address, amounts, and the job is to get that row into a web form. Done by hand it's a cell-at-a-time shuffle: click the cell, copy, switch to the form, click the field, paste, repeat, and hope you didn't skip a column.

This guide shows a workflow for filling web forms from spreadsheet data without copying field by field, using FillWise, a Chrome extension we build. One honest note up front: this is about getting a row's data into a form, not about uploading the spreadsheet file. We'll explain exactly how that works below.

Why cell-by-cell copying is the slow part

The spreadsheet is fine. The friction is the crossing from spreadsheet to form:

• One row, many fields. Each cell has to find its matching field, and the order in the sheet rarely matches the order on the form.
• Column drift. Copy the wrong cell once and the whole row lands shifted, which you often notice only after submitting.
• Format mismatches. Dates and phone numbers stored one way in the sheet have to be re-typed to match what the form expects.
• It's per-row, forever. A hundred rows is a hundred passes of the same manual shuffle.

None of this is analysis. It's transcription between two tools, which is what's worth automating.

The workflow

FillWise is a Chrome extension with a side panel. Instead of copying cell by cell, you copy the whole row as text, paste it into the panel, open the form, and click Fill form. The AI reads the pasted data, matches each value to the right field on the page, and enters it. You review and submit.

One-time setup

1. Install FillWise from the Chrome Web Store.
2. Sign in with Google or with a one-time code sent to your email. The free plan starts with 20 fills and then tops back up to 5 a week, enough to try it on your real forms before paying anything.

From a spreadsheet row to a form

1. In your spreadsheet, select the row (or the cells you need) and copy. Pasting a row copies the values as tab-separated text, which is exactly what the panel needs.
2. Open the form in a Chrome tab, open the FillWise side panel, and paste. Including the header row alongside the values helps the AI know what each value is, but it works from the values either way.
3. Click Fill form. Each value is matched to its field by meaning, not by position, so column order in the sheet doesn't have to match field order on the form.
4. Review against the row and submit.

Because matching is by meaning, the same paste fills forms with different field layouts without any per-form setup.

Working through many rows

For a batch, keep the form tab and the panel open and go row by row: paste the first row, fill, submit, then paste the next. The panel doesn't reset between fills, so the loop is copy row, paste, fill, submit.

What it doesn't do

This is the honest part, and worth reading before you start:

• It doesn't take a spreadsheet file. You don't upload an .xlsx or .csv. You copy the row (or a screenshot of it) and give the panel that. Accepted attachments are images and PDFs, not spreadsheet files. PDF forms are the exception: Bulk fill in the FillWise account takes the CSV or Excel file itself and fills one copy of the form per row, see the bulk fill guide.
• It fills one form at a time. It doesn't loop through a whole sheet and submit every row on its own. You paste and submit per row; the speed comes from skipping the cell-by-cell copying, not from unattended bulk submission.
• It doesn't build the form. It fills forms that already exist on the page you open.

What to check by hand

Autofill removes the typing, not the responsibility.

• Spot-check that values landed in the fields you expected, especially on rows where the sheet has blank cells.
• Confirm dates and numbers, which the AI reformats to fit the field; make sure the reformatting matches your intent.
• Watch dropdowns: the AI selects an option, but confirm it's the one the row meant.

Data and privacy

Whatever you paste is sent encrypted to our servers, read by the AI to produce the field values, and is not stored after processing. Nothing is sold or used to train models. The specifics are in our privacy policy.

Pricing

The free plan starts with 20 fills and then tops back up to 5 a week, no card required, enough to run real rows through your actual form and judge the result. Paid plans are on the pricing page.

FAQ

Can I upload an Excel or CSV file? Not for web forms. You copy the row from the sheet and paste it as text, or attach a screenshot of it; the AI reads either. Spreadsheet files themselves aren't accepted as attachments in the extension, only images and PDFs are. For PDF forms, yes: Bulk fill in the account reads a CSV or XLSX file.

Does column order in my sheet have to match the form? No. Matching is by meaning, using each field's label and type, so the value for "email" goes to the email field wherever it sits. Including the header row in your paste makes the matching more reliable.

Can it fill every row of my sheet automatically? It fills one form at a time. You go row by row, pasting and submitting each, which is much faster than copying cell by cell but is not unattended bulk submission.

What if the form is a PDF, not a web page? FillWise fills fillable PDFs too; see the PDF automation guide. To fill the same PDF form for every row of a sheet at once, use Bulk fill in the account, described in the bulk fill guide.

Try it on the next row you would otherwise copy cell by cell: install FillWise, open the form, and paste the row. The free plan starts with 20 fills, no card required.
