Tired of 'Tsukiawase'? Complete Guide to AI-Powered Data Matching
Suffering from eye strain and stiff shoulders due to daily data matching? Discover the limits of 'Visual Checks' and how to use AI to zero out that workload.
Right monitor and left monitor. Paper slips and Excel on screen. Moving your eyes back and forth, checking numbers… “Tsukiawase” (Matching) work.
By evening, your vision blurs, your head feels heavy… That’s not because you aren’t working hard enough. It’s because “Human eyes are not built for comparing massive data.”
This article explores the limits of manual data matching and introduces AI-powered solutions that can transform your workflow.
What is “Tsukiawase”?
Definition
Tsukiawase (突き合わせ) is the Japanese term for data matching or reconciliation - the process of comparing two sets of data to ensure they match.
| Japanese | English Equivalent | Context |
|---|---|---|
| 突き合わせ | Data matching | General |
| 照合 | Verification | Formal |
| 突合 | Reconciliation | Accounting |
Common Matching Tasks
| Source | Target | What to Check |
|---|---|---|
| Invoice | Purchase Order | Amounts, quantities |
| Delivery Note | Order | Items received |
| Bank Statement | Ledger | Transactions |
| Inventory Count | System Records | Stock levels |
Is That Stiff Shoulder Caused by “Tsukiawase”?
Physical Symptoms of Manual Matching
| Symptom | Cause | Frequency |
|---|---|---|
| Eye strain | Screen staring | Very common |
| Stiff shoulders | Poor posture | Very common |
| Headaches | Visual fatigue | Common |
| Back pain | Prolonged sitting | Common |
| Wrist pain | Repetitive movements | Moderate |
Psychological Impact
| Impact | Description | Long-term Effect |
|---|---|---|
| Stress | Fear of missing errors | Burnout |
| Anxiety | Deadline pressure | Work avoidance |
| Boredom | Repetitive nature | Disengagement |
| Frustration | Finding many errors | Demotivation |
The Limits of “Visual Checks”
It is said that a human can concentrate on comparing data accurately for only a few dozen minutes. Beyond that, the brain fatigues, and mistakes occur.
Cognitive Limitations
| Phenomenon | Description | Result |
|---|---|---|
| Gestaltzerfall | Characters become meaningless symbols | Cannot spot differences |
| Inattentional blindness | Missing obvious errors | Errors slip through |
| Slips | Assuming matches when they don’t | False positives |
| Fatigue drift | Accuracy drops over time | More errors later |
Error Rates by Time
| Duration | Accuracy | Error Rate |
|---|---|---|
| 0-30 min | 98% | 2% |
| 30-60 min | 95% | 5% |
| 60-90 min | 90% | 10% |
| 90+ min | 85% | 15% |
Willpower won’t fix this. You need to change the system.
Traditional Matching Methods
Method 1: Dual Monitor Comparison
Process: Display source on left screen, target on right, compare visually.
| Advantage | Disadvantage |
|---|---|
| No setup needed | Highly error-prone |
| Works anywhere | Very slow |
| Flexible | Causes eye strain |
Method 2: Excel VLOOKUP
Process: Use formulas to find matching records.
| Advantage | Disadvantage |
|---|---|
| Automated matching | Cannot handle variations |
| Fast for exact matches | #N/A on slight differences |
| Free (Excel included) | Formula maintenance |
Method 3: Highlighting Differences
Process: Use conditional formatting to show mismatches.
| Advantage | Disadvantage |
|---|---|
| Visual indication | Still requires setup |
| Good for numbers | Text variations missed |
| Built into Excel | Manual configuration |

How AI Matching Works
Step 1: Upload
Drag and drop both files (PDF, CSV, Excel, etc.)
Step 2: AI Analysis
AI reads and understands both documents, identifying comparable fields.
Step 3: Intelligent Matching
AI compares data, accounting for:
- Text variations (“Inc.” vs “Corporation”)
- Number formatting (1,000 vs 1000)
- Date formats (01/23 vs Jan 23)
- Spelling variations
Step 4: Exception Display
Only discrepancies are highlighted for human review.
Case Study: Before and After
Before: Manual Matching
| Metric | Value | Impact |
|---|---|---|
| Time spent | 3 hours/day | Lost productivity |
| Errors missed | 2-3/week | Financial risk |
| Employee satisfaction | Low | Turnover risk |
