How to automate repetitive data entry in your browser

November 6, 2026 · 6 min read · By the Aullevo team

Data entry is the quiet time sink of office work. Registering for supplier portals, submitting expense claims, updating the same contact details on ten websites, entering student information into a school system: each task takes a few minutes, but they add up to hours each week. Most of it is copying information you already have from one place into another.

Signs your data entry is worth automating

  • You type the same values (company name, tax number, address, contact person) more than a few times a week.
  • You keep a document open just to copy answers from it.
  • Mistakes from retyping, such as a wrong digit in a phone number, cause rework.
  • You fill the same form for many items, such as a list of links or records.

Check for a better door first

Before automating a web form, ask whether the system offers a direct route: a spreadsheet import, a bulk upload, an API, or an integration with the software you already use. If it does, that is almost always faster and more reliable than filling forms one by one. Browser automation is for the many cases where the web form is the only way in.

Your options, from simplest to most powerful

  1. Clipboard managers keep a history of what you copied, so you are not switching windows for every value.
  2. Text expanders turn short abbreviations into longer text. Ideal for repeated sentences and email addresses.
  3. Form-filler extensions store your data as structured profiles and fill entire pages at once, including dropdowns, checkboxes, and file uploads.
  4. Browser macros record clicks and keystrokes and replay them. Useful for one specific, stable page, but fragile when the layout changes.
  5. RPA and scripting (UiPath-style platforms, Playwright, Selenium) automate complete workflows across systems. Powerful, but they need technical skills, testing, and maintenance.

A practical workflow with a form filler

  1. Standardise your data once. Decide on one spelling of your company name, one address format, and one phone format, and save them in a profile.
  2. Create separate profiles for separate contexts, for example Company, Personal, and a Custom profile for a client you work with often.
  3. Add context hints to unusual fields so the matcher knows that "VAT ID" and "Tax registration number" mean the same thing.
  4. For batches, queue the pages you need to fill. Aullevo's Multi-link queue, for example, lets you add several links and fill them in one go.
  5. Review each page before you submit. Speed is only useful if the result is right.

Tip: Do the maths before choosing a tool. If 40 forms a month take 8 minutes each, that is more than 5 hours. Cutting each to 2 minutes gives you 4 hours back every month.

Keep data entry accurate and safe

  • Prefer tools that store data encrypted on your device rather than in someone else's cloud.
  • Keep bank and identification numbers out of automated profiles unless the tool lets you mark them sensitive.
  • Update the profile the moment something changes, such as a new address, so old data is not reused.
  • Spot-check a sample of automated entries regularly, the same way you would review a colleague's work.

Frequently asked questions

What is the best tool to automate data entry?

It depends on volume and skills. For individuals and small teams filling many different websites, a form-filler extension is usually the best balance. For one high-volume internal process, RPA or a script may be worth the setup. If the system has an import or API, use that first.

Can I fill a web form from a spreadsheet?

Many systems offer a CSV or spreadsheet import, which is the most reliable option. Otherwise you can paste spreadsheet values into a form-filler profile, or use a script or RPA tool that reads rows and fills the form for each.

Is automating data entry accurate?

Usually more accurate than retyping, because the same saved value is used every time. Errors come from outdated saved data or fields that are matched incorrectly, so review each form before submitting.
