Superslurp

SuperSlurp is a Utility for Parsing & Extracting Receipts via Savage Layers of Unreadable Regex & Processing

It parses Super U PDF receipts. Can generate a JSON from a receipt, or a JSON aggregate from multiple receipts for consumption from another tools, or generate an HTML report directly.

The parser understands the intricacies of French cuisine, for example it knows a Reblochon fermier from a laitier, as per the French government's official AOP specification.

Useful when you want to display cheese consumption intensity in €/day inside Grafana, or detect sneaky shrinkflation via fat-content drift on your favorite fromage blanc.

Quick start

Install

pip install superslurp

Run

Generate a report from directory of PDF receipts:

superu-report receipts/*.pdf -o report.html

Then open report.html

Synonyms

Receipts are full of abbreviations (REBL.SAV. for REBLOCHON SAVOIE). ~200 built-in synonyms handle the common ones. To add your own, create a JSON file mapping abbreviations to full names:

{
  "FAR.FROM": "FARINE DE FROMENT",
  "FROM": "FROMAGE"
}

superu-report receipts/*.pdf --synonyms extra.json -o report.html

Order matters — put multi-word abbreviations before their single-word parts. Here FAR.FROM comes before FROM, so a receipt line FAR.FROM correctly becomes FARINE DE FROMENT. If FROM came first, it would be replaced by FROMAGE and you'd end up with flour cheese instead of wheat flour.

Use --no-default-synonyms to disable the built-in set entirely.

Parse example

REBL.SAV.AOP.FRM.LC BIO BQT.X12 450G 32%MG 8,61 € 11 is parsed as:

{
  "raw": "REBL.SAV.AOP.FRM.LC BIO BQT.X12 450G 32%MG  8,61 €  11", // debug=True
  "name": "REBLOCHON",
  "price": 8.61,
  "bought": 1,
  "units": 12,
  "grams": 450.0,
  "fat_pct": 32.0,
  "properties": {
    "bio": true,
    "milk_treatment": "cru",
    "production": "fermier",
    "label": "AOP",
    "packaging": "BARQUETTE",
    "origin": "SAVOIE",
  },
  "...": "...",
}

Aggregate output

Products are grouped under a canonical name using fuzzy matching (difflib, threshold 0.90):

{
  "stores": [{ "id": "123_456", "store_name": "...", "location": "..." }],
  "sessions": [{ "id": 1, "date": "2025-01-15 10:00:00", "store_id": "123_456" }],
  "session_totals": [{ "session_id": 1, "date": "2025-01-15", "total": 42.5 }],
  "session_category_totals": ["..."],
  "category_rolling_averages": ["..."],
  "products": [
    {
      "canonical_name": "OEUFS",
      "observations": [
        {
          "original_name": "OEUFS PLEIN AIR MOYEN",
          "session_id": 1,
          "price": 3.15,
          "unit_count": 12,
          "price_per_unit": 0.2625,
          "bio": true,
          "...": "...",
        },
      ],
    },
  ],
}

Developer guide

Pipeline steps

superu-report runs parse → aggregate → HTML in one shot. During development you can run each step individually to avoid re-doing everything when iterating on a single stage:

# 1. Parse a single receipt PDF → JSON
superu-receipt-parser receipt.pdf -o receipt.json

# 2. Aggregate multiple parsed JSONs
superu-aggregate-parsed-receipt receipts/ -o aggregate.json

# 3. Generate report from an existing aggregate
superu-report-from-aggregate aggregate.json -o report.html

# Or pipe step 2 → 3
superu-aggregate-parsed-receipt receipts/ | superu-report-from-aggregate - -o report.html
