Migrating from Word and Excel to nutrition software: the checklist

Updated 15 June 2026 · 4 min read

Many dietitians and nutritionists start their practice with whatever tools are at hand: a Word document for meal plans, an Excel sheet to track patients, an inbox for everything else. It works, at first. Then the patient list grows, the files multiply, and Sunday evenings disappear into reformatting tables instead of resting.

Moving to dedicated software is not a leap into the unknown. Done right, the whole operation takes a few hours spread over a week, and you lose no data. Here is the checklist we recommend.

Before migrating: take inventory

Before touching anything, lay out what you actually use. Most practices are surprised to find they rely on three or four recurring files, no more.

List:

  • Your active patients: name, contact details, date of birth, reason for consultation.
  • Your plan templates: the outlines you reuse from one patient to the next.
  • Your measurement tracking: weight, goals, milestones.
  • Your invoicing: current numbering, legal mentions, VAT rate applied.
  • Your email templates: appointment confirmation, plan delivery, reminders.

This inventory is the backbone of the migration. Anything not on it probably does not need to move.

Step 1: clean up your data

A migration is the perfect moment to declutter. There is no point importing ten years of lost-touch patients or outdated plans.

  • Archive patients inactive for more than two years into a separate file.
  • Remove duplicates (the same patient entered twice with a typo).
  • Standardise date and phone formats in your spreadsheet: a clean column imports without a hitch.

An hour of cleanup upfront saves you half a day of fixes after the import.

Step 2: prepare a clean import file

Most nutrition software accepts a patient import in CSV format (a universal spreadsheet file). The goal: one row per patient, one column per piece of information.

A few simple rules:

  • A single sheet, with no merged cells.
  • Clear column headers on the first row (Last name, First name, Email, Phone, Date of birth).
  • No colours or formatting: they are not imported and serve no purpose.

If you are unsure about the expected format, ask your provider for a template. At thenutritionist, we provide a ready-to-fill CSV template.

Step 3: import and verify

Run the import on a small batch first: five to ten patients. Check that accents, dates and emails are correct, then import the rest.

Right after the import, check three things:

What to checkWhy
Accents and special charactersBad encoding turns "Léa" into "Léa"
Dates of birthDay/month order can flip depending on the tool
EmailsA wrong address blocks plan and reminder delivery

Step 4: rebuild your templates

Your plan outlines and standard emails are what save you the most time day to day. Rebuild them once and for all inside the software.

Take the chance to improve them: good software lets you start from a template, tailor it for each patient, and even generate an assisted draft that you review before sending. The pen stays in your hand, but the blank page is gone.

Step 5: switch over gradually

You do not have to move everything overnight. The calmest approach:

  1. Enter new patients straight into the software.
  2. Migrate active patients as they come in for their next consultation.
  3. Keep your old file read-only for a month while you find your footing.

Within four to six weeks, the old system is just an archive.

What about your health data?

Migrating is also a chance to ask a question that is easy to dodge when everything sits on your own computer: where does your patients' data actually live? An Excel file on a hard drive is neither backed up, nor encrypted, nor aligned with the requirements that apply to health data.

Serious software hosts your records securely and lets you export them at any time. That is peace of mind, for you and for your patients.

In short

Migrating from Word and Excel to nutrition software comes down to five steps: take inventory, clean up, prepare a clean CSV, import while verifying, then rebuild your templates and switch over gradually. The effort is measured in hours; the payoff is measured in Sundays reclaimed.
