sahit-sai /csv-to-sif — CSV to SIF Converter
Converts a CSV, Excel, or Google Sheets product list into a SIF (Standard Interchange Format) file for import into dealer and procurement systems like Hedberg, CAP, CET, Cyncly Worksheet, ProjectMatrix, Studio Webware, and Design Manager.
When to Use
- Sending a specification to a dealer for quoting
- Importing product data into a dealer management system
- Sharing a standardized product list with procurement
- Converting an FF&E schedule into a format dealers expect

Step 1: Accept Input
CSV file:
/csv-to-sif ~/Documents/project/product-data-import.csv
Google Sheet:

Saarinen Table 54,Knoll,164-500,1,4750,Arabescato/White,Dining
Step 2: Choose Target System
Ask which dealer system the SIF file is for (affects which field codes to use):
Target system:
1. Standard (Hedberg, CAP, ProjectMatrix) — default
2. CET / Configura (SPEC)
3. Cyncly Worksheet (CAPSIF)
4. Design Manager
Default to Standard if not specified. The main differences:
- Standard: MC for manufacturer, PL for price, QT for quantity
- CET: EC for manufacturer, standard pricing
- Cyncly: MG/MN for manufacturer, I1/I2 for pricing, PRC for category
- Design Manager: Standard + DXSC, DXBD, DXLC, DXLN extensions
Step 3: Map Columns
Auto-detect column mappings from header names:
| CSV Column (common names) | SIF Field |
|---|---|
| Product Name, Name, Description, Product | PD |
| SKU, Model, Part Number, Product Number | PN |
| Brand, Manufacturer | MC + MN |
| Qty, Quantity, Count | QT |
| Price, List Price, Unit Price | PL |
| Finish, Color, Configuration | OD |
| Room, Location, Area, Tag, Side Mark | TG |
| Category | GC |
| Weight | WT |
| Discount, Discount % | S- |
| URL, Product URL, Link | ProductURL |
| Image, Image URL | ImageURL |
| W, D, H (dimensions) | AD (with AN=DIM) |
If using the master 33-column schema (defined in ../../schema/product-schema.md):
See ../../schema/sif-crosswalk.md for the full column-to-SIF mapping. Key fields:
| Column | SIF Field |
|---|---|
| A (Category) | GC |
| B (Brand) | MC + MN |
| E (Product Name) | PD |
| I (SKU) | PN |
| J (Link) | ProductURL |
| L-P (W, D, H, Seat H, Unit) | AD (with AN=DIM) |
| Q (Weight) | WT |
| R (Materials) | AD (with AN=MAT) |
| S (Colors/Finishes) | OD (with ON=FIN) |
| T (Selected Color/Finish) | OD (primary, replaces S if present) |
| U (List Price) | PL |
| AC (Image URL) | ImageURL |
| AD (Tags) | TG |
If the mapping is ambiguous, ask the user to confirm.
