SharePoint Forms365 vs InfoPath: what you gain and what you lose

Most comparisons of this shape are written to make the old product look embarrassing. That would be dishonest here. InfoPath was a genuinely good tool, and a lot of the forms it built are still running because they still work. If you are reading this, you are probably not choosing between the two. You are being made to leave one of them, and you want to know what the new thing costs you.

So this page is organised around that question rather than a sales one.

Why you are moving at all

InfoPath Forms Services reached end of support, and InfoPath Designer stopped receiving updates a long time before that. Nothing breaks the morning after a support date passes, but the runway is finite and every month of delay lands the rebuild on a team with less context about why the original rules were written that way. We covered the timeline and the full field of replacements in InfoPath end of life in 2026.

This page assumes you have already decided to move and are weighing Forms365 specifically.

Four things InfoPath genuinely did better

Offline form filling. InfoPath's rich client let people fill a form on a plane and submit on landing. Forms365 is a browser runtime inside SharePoint. There is no offline story, and honestly there is not a good one anywhere in the modern stack. If offline capture is a hard requirement, neither we nor Power Apps nor Nintex will give you back what InfoPath had.

Complex nested repeating structures. InfoPath's repeating sections could nest several levels deep against an arbitrary XML schema. Our LinkedList component handles parent and child cleanly, which covers line items, attendees and delivery lines, but it is one level. A form with repeating groups inside repeating groups will need restructuring rather than porting.

Arbitrary XML as the data source. InfoPath bound to whatever XML schema you handed it. We bind to a SharePoint list. That is a real constraint, and it is the single most common reason a legacy InfoPath form cannot be migrated as-is. The upside is that your data lands somewhere queryable, permissioned and visible in the same place as everything else, instead of in an XML blob nobody can report on.

Desktop-grade printing. InfoPath print views were precise. Browser printing is not, for anybody.

Say those out loud before you start the rebuild, because two of them are the kind of thing that surfaces halfway through and stalls a project.

What you get in exchange

The form is not a black box any more. An InfoPath form is a file. Its rules are visible only to somebody with Designer installed and the patience to open it. A Forms365 form is a designed schema with its rules in plain conditions anybody with access can read in the browser. The person who inherits the form in 2030 can find out what it does.

It survives schema drift. Rename a column in the list and an InfoPath form breaks in a way that requires Designer to repair. Our schema reconciliation re-derives every schema-driven property on load, so a renamed or retyped column resolves itself. Over a decade of a form's life this matters more than any feature on a comparison table.

AI does the boring half of the rebuild. Point the form builder at a Word document or describe the form in a sentence and you get a starter schema to correct rather than a blank canvas to fill. When you are migrating thirty forms rather than one, this is the difference between a quarter and a fortnight.

It works on a phone. InfoPath forms in a browser on a small screen were, at best, a compromise. Ours are responsive by default.

No client install, ever. Nothing to deploy to desktops, nothing to version, nothing that breaks when someone gets a new laptop.

Mapping the concepts

Most of the InfoPath vocabulary has a direct equivalent, which makes the rebuild less alarming than it first looks.

InfoPath	Forms365 equivalent
Data source fields	SharePoint list columns
Views	Pages or tabs on one form
Rules (formatting)	Conditional formatting and visibility rules
Rules (validation)	Validation rules and requiredIf
Rules (action)	Action buttons and the f365 JavaScript API
Repeating section	LinkedList (parent and child)
Data connection to list	Lookup column or LinkedList
Submit to library	Save to the bound list
Code behind (C#)	Form JavaScript in the Code drawer

The field-by-field version of that mapping, with the gotchas around data connections, is in Migrating an InfoPath form to a SharePoint list form.

So should you pick us

If your InfoPath form is a list-shaped business form (a request, an intake, a register, an approval), then yes, we think we are the most direct replacement. That describes the large majority of surviving InfoPath forms.

If your form is genuinely a document with deep nesting, arbitrary XML, or offline capture, be honest about it early. Some of those belong in Power Apps, some belong in a custom build, and a few of them turn out to be a process that should have been three simple forms all along.

If you have thirty forms and no idea which are which, start by inventorying them rather than by choosing a product. Half of any InfoPath estate is usually dead, and the rebuild you are dreading is smaller than it looks.

The 5-minute quickstart is the cheapest way to test one form before committing to anything.
