OCR Parser Pattern Catalog
Extraction regexes and test cases for the ocr-data-extraction skill.
Phone Numbers
/\(?\d{3}\)?[\s.\-]*\d{3}[\s.\-]*\d{4}/
Matches: (555) 123-4567, 555-123-4567, 555.123.4567, 8653353874, (865) 235-0156
Normalize: strip all non-digits after match.
VIN (17-char)
/\b[A-HJ-NPR-Z0-9OIQ]{17}\b/i
Lenient: accepts O (common OCR error for 0), I (for 1), Q (for 0).
Normalize: v.toUpperCase().replace(/O/g,'0').replace(/I/g,'1').replace(/Q/g,'0')
Standard VIN: 17 chars, alphanumeric, no I/O/Q in real VINs, but OCR produces them.
Dates
Priority order of patterns:
// 1. YYYY-MM-DD or YYYY/MM/DD
/(\d{4})[\/\-.](\d{1,2})[\/\-.](\d{1,2})/
// 2. MM/DD/YYYY or MM/DD (year defaults to current)
/(\d{1,2})[\/](\d{1,2})(?:[\/](\d{4}))?/
// 3. "Jan 15, 2024" or "January 15 2024"
/(jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec)[a-z]*\s+(\d{1,2})(?:[,\s]+(\d{4}))?/i
Normalize all to YYYY-MM-DD.
Times
/\b(\d{1,2}):(\d{2})\s*(AM|PM|am|pm)?\b|\b(\d{1,2})\s*(AM|PM|am|pm)\b/
Matches: 9:00 AM, 14:00, 1:30PM, 8am, 8 AM
Normalize to 24hr HH:MM. PM adds 12 unless hour=12. AM at 12 becomes 00.
Duration
/\b(\d+)\s*(?:min|minutes?|hrs?|hours?)\b/i
Matches: 60 min, 1 hour, 2 hours, 90min
If "hour/hr" in match text, multiply value by 60.
Vehicle Detection
Year pattern: /\b(19|20)\d{2}\b/
Make keywords (case-insensitive):
ford|chevy|chevrolet|toyota|honda|nissan|bmw|mercedes|audi|dodge|jeep|gmc|ram|hyundai|kia|subaru|mazda|vw|volkswagen|lexus|acura|infiniti|cadillac|buick|chrysler|lincoln|tesla|volvo
Advisor + RO Code
/^([A-Z][a-z]+)\s+(\[[^\]]+\])\s+(.*)/
Strip group 1 (advisor name) and group 2 (RO code). Save group 2 as note. Return group 3 (service description).
Boundary Detection
Primary: multi-space gap before name+phone
/\s{2,}(?=\S+(?:\s+\S+){0,1}\s*$)/
Finds 2+ spaces before the last 1-2 words that precede a phone/VIN marker.
Fallback: capitalized name before phone
/([A-Z][A-Za-z]+(?:\s+[A-Z][A-Za-z]+){0,1})\s*$/
When no multi-space gap exists, detect last 1-2 capitalized words as the next appointment's name.
Header/Noise Filters
# Separator lines
/^[\-–=_*#]{3,}$/
# Short all-caps headers (< 25 chars)
/^[A-Z\s]+$/ (with length check)
# Known header words (case-insensitive)
/^(schedule|appointments|roster|calendar|upcoming|date|time|customer|name|phone)$/i
# Table header row detection
/\b(name|phone|date|time|service|vehicle|vin|customer|appointment|mileage|advisor|status)\b/i
