Upload messy.
Download perfect.
AI-powered spreadsheet parsing that handles any format, any region, any mess. Your data, perfectly sorted into the exact columns you need.
How It Works
From messy upload to perfect output in under 60 seconds. No technical knowledge required.
Upload Any Spreadsheet
Drag and drop .xlsx, .csv, or .xls. We handle files with thousands of rows, messy formatting, merged cells, and mixed data types.
Our system reads your file and auto-detects the structure. No configuration needed upfront.
Tell Us What You Need
Pick a template like "Canadian Mailing Address" or describe it in plain English: "Split Column B into street, city, province, postal code."
You choose the exact output columns. Add custom rules. The system adapts to your format, not the other way around.
Preview & Verify
Review 20 parsed sample rows before processing the full file. Flag anything that looks off. The system learns from your corrections.
Every ambiguous row is highlighted. You decide, not the machine.
AI Parses Everything
The full file is processed. A custom-generated parser handles deterministic patterns. AI steps in only for ambiguous rows.
Two-way verification runs automatically: every word in your source is accounted for in the output, and vice versa.
Download Perfect Data
Get your clean .xlsx with source columns preserved alongside parsed columns. Includes a verification report proving zero data loss.
Your original data is never modified. Parsed columns are added alongside, so you can always compare.
Smart enough to know
what it's looking at.
Not regex. Not simple splitting. Actual understanding of what your data means in context. Built from parsing thousands of real-world edge cases.
Any Region, Any Format
Canadian addresses with multi-word cities (Niagara-on-the-Lake, Sault Ste. Marie), US ZIP+4, UK postcodes, Australian formats. The system identifies the region and adapts automatically.
Any Spreadsheet Structure
One column with everything jammed in. Ten columns partially parsed. CSV exports from any CRM, government database, or property assessment system. Mixed formats within the same file.
Contextual Disambiguation
Building names vs address components. Floor numbers vs unit numbers. Company names vs person names. The system understands context, not just patterns.
Learns Your Patterns
Save parsing templates for recurring file formats. Add custom rules ("STN always means suite for this client"). Every correction makes future parses more accurate.
Smart Edge Case Handling
PO BOX vs street address detection. Rural routes. General delivery. ATTN and C/O extraction. Direction vs city disambiguation (NORTH YORK is a city, not north + York).
AI Writes the Parser, Not Every Row
Our AI generates a custom parser for your specific file format. The parser runs deterministically on all rows. AI only re-engages for genuinely ambiguous cases. This keeps costs low and accuracy high.
Accuracy isn't a feature.
It's the product.
When you send a parsed mailing list to a client, you can't have missing addresses, swapped fields, or dropped data. We built the verification system first, then the parser around it.
Two-Way Verification
Every word in your source maps to an output field (forward). Every word in the output traces back to the source (reverse). Mathematical proof of zero data loss.
Human Review Queue
Ambiguous rows are flagged for your review before download. You approve every edge case. The system never guesses silently.
Source Preservation
Your original data is never modified. Parsed columns are added alongside. Even source errors are preserved as-is. Your data, your truth.
Confidence Scoring
Every row gets a confidence score. 95%+ is auto-resolved. Below 95% is flagged. Below 80% requires manual approval. No silent failures.
Built for people who
can't afford mistakes.
