Why Excel Check-in No Longer Works for Events

TL;DR: Excel check-in breaks down at real events because name lookup takes 20-30 seconds per guest (versus 1-5 seconds with QR), drives 5-10% check-in error rates (especially with Vietnamese diacritical names), and offers no real-time data, fraud prevention, or automated reporting. For any event with 50+ guests, QR code check-in delivers 10-15x the effectiveness at an affordable cost.

Excel — Familiar but Outdated

Excel spreadsheets are the most common check-in method at small-to-medium events in Vietnam. Everyone knows Excel, no software investment needed, and it’s “free.” But under the pressure of real events, Excel reveals serious limitations.

The 5 Biggest Problems with Excel Check-in

1. Long Queues — Frustrated Guests

Reality: With 200 guests, a staff member using Excel needs an average of 20-30 seconds to find a name (Ctrl+F or scroll), verify information, and mark attendance. If 50 guests arrive simultaneously (very common in the first 15 minutes), the queue stretches to 20-40 minutes.

Comparison: QR code check-in handles the same guests in 3-5 seconds/person. Maximum queue time: 5 minutes.

Real story: At a 300-guest seminar in Hanoi, organizers used 3 Excel files on 3 laptops. Guests waited 45 minutes in the sun. Many left. The event started 30 minutes late.

2. High Error Rate — Especially with Vietnamese Names

Reality: Vietnamese names with diacritical marks are an Excel “nightmare.” “Nguyễn Văn An” and “Nguyễn Văn Ân” are easily confused. “Trần Thị Hồng” and “Trần Thị Hạnh” might be marked on the wrong row. With 500+ names, error rates reach 5-10%.

Common errors:

• Finding the wrong person due to similar/identical names
• Marking the wrong row in Excel (pressing Enter on the wrong cell)
• Missing guests due to misspelled names in the list
• Duplicate check-ins when multiple staff use the same file
• Failing to detect guests arriving on the wrong day/session

Comparison: QR code check-in has an error rate below 0.1%. Each code is unique, the system validates automatically.

3. No Real-time Data

Reality: Organizers want to know “how many guests have entered?” but with Excel, the answer is “hold on, let me compile.” Nobody knows immediately:

• How many guests have checked in
• Which gate is congested
• Whether VIPs have arrived
• How many guests haven’t shown up yet

Consequence: Organizers make blind decisions — not knowing whether to delay the event, call in more staff, or send reminders to no-shows.

4. Fraud Prevention is Nearly Zero

Reality: With Excel, check-in staff can’t remember 500+ faces. Anyone can:

• Read names from the publicly available registration list
• Borrow someone else’s ticket
• Show a screenshot of a friend’s confirmation email
• Check in twice at two different gates

Comparison: QR codes can only be scanned once. Used codes are immediately locked across the entire system.

5. Post-event Reporting — A New Nightmare

Reality: After the event, staff must:

• Compile data from multiple Excel files (if using multiple check-in points)
• Resolve data conflicts (two people editing simultaneously)
• Reformat to create reports
• Calculate check-in rates manually

This process takes 2-4 hours and still has errors.

Comparison: QR code systems automatically generate reports as soon as the event ends: check-in rates, peak hours, breakdown by ticket type.

Detailed Comparison

Criteria	Excel	QR Code (QRS)
Check-in speed	20-30 seconds/person	1-2 seconds/person
Error rate	5-10%	< 0.1%
Real-time data	No	Yes
Fraud prevention	No	Automatic
Multiple check-in points	Very difficult (file conflicts)	Easy (auto-sync)
Post-event reports	2-4 hours, manual	Automatic, instant
Cost	Free	From affordable plans
Technical skill needed	Know Excel	Open app and scan
Phone compatibility	No	Yes (iOS, Android)
Offline capability	Yes (local file)	Yes + auto-sync

When Is Excel Still Appropriate?

Excel can still be used for:

• Events under 30 guests: Small meetings, mini workshops
• Internal events: Staff all know each other, no access control needed
• Zero budget: Truly cannot spend anything

However, for any event with 50+ guests, the risks of using Excel far outweigh the “free” benefit.

The True Cost of Excel

Many people think Excel is free, but the real costs include:

• Extra staff: Need 2-3x more staff than QR check-in
• Time: Slow check-in = delayed event start
• Errors: Wrong check-ins = complaints and issues
• Reporting: 2-4 hours of manual compilation after each event
• Reputation: Long queues = guests posting photos on social media = bad PR

When tallied up, “free” Excel is actually more expensive than QR code solutions.

How to Switch from Excel to QR Code

Step 1: Export Your List from Excel

Export a CSV file from Excel — this is the only step needed with your existing data.

Step 2: Import into QR Code System

Upload the CSV file to QRS CMS. The system automatically generates QR codes for each guest.

Step 3: Send QR Codes to Guests

QRS automatically sends emails containing QR codes to the entire list, or you can send SMS.

Step 4: Check In by Scanning

Staff open the scanning app on their phones. No laptops needed, no Excel required.

The entire transition takes under 30 minutes for one event.

Conclusion

Excel check-in was once a reasonable temporary solution, but in 2026, it’s an unnecessary risk. Slow speed, high errors, no real-time data, and no fraud prevention — these limitations directly impact event quality. At an affordable cost, QR code solutions like QRS deliver 10-15x the effectiveness of Excel, with a professional experience for both organizers and guests.

Frequently Asked Questions

How many seconds per guest does Excel check-in take versus QR?

According to the comparison in this article, an Excel lookup takes roughly 20-30 seconds per guest (finding the name with Ctrl+F or scrolling, verifying, and marking attendance), while QR code scanning completes check-in in 1-5 seconds per person.

At what event size does Excel stop being appropriate?

Excel remains reasonable only for events under 30 guests, internal events where everyone knows each other, or situations with a truly zero budget. For any event with 50 or more guests, the risks of slow queues, errors, and lack of real-time data outweigh the “free” benefit.

Why is Excel especially error-prone for Vietnamese names?

Vietnamese names with diacritical marks are easily confused in a text list — for example “Nguyễn Văn An” and “Nguyễn Văn Ân”, or “Trần Thị Hồng” and “Trần Thị Hạnh” — and with 500+ names the error rate reaches 5-10%. QR codes sidestep this entirely because each code is unique and validated automatically by the system, bringing the error rate below 0.1%.

How does QR check-in prevent duplicate or fraudulent entry?

Each QR code can only be scanned once; once used, the code is immediately locked across the entire system and across every check-in gate. This prevents a guest from borrowing someone else’s ticket, screenshotting a confirmation email, or checking in twice at different gates — all of which are possible with an Excel list that staff cannot verify against.
