/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

Rules

• Each line is one field: CODE=VALUE
• Lines terminated by CRLF
• Blank line between records
• PN starts a new record — must come first in each record
• ON/OD and AN/AD pairs must stay together
• No embedded line breaks within a field value
• Empty values use CODE= with nothing after the equals sign

Step 1: Accept Input

CSV file:

/csv-to-sif ~/Documents/project/ffe-schedule.csv

Google Sheet:

/csv-to-sif 1FMScYW9guezOWc_m4ClTQxxFIpS6TNRr373R-MJGzgE

Pasted CSV:

/csv-to-sif
Product,Brand,SKU,Qty,Price,Finish,Room
Eames Lounge Chair,Herman Miller,670,3,5695,Walnut/Black Leather,Executive Lounge
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):

Column	SIF Field
A (Link)	ProductURL
C (Product Name)	PD
E (SKU)	PN
F (Brand)	MC + MN
J (Category)	GC
K-O (W, D, H, Seat H, Unit)	AD (with AN=DIM)
P (Weight)	WT
Q (Materials)	AD (with AN=MAT)
R (Colors/Finishes)	OD (with ON=FIN)
S (Selected Color/Finish)	OD (primary, replaces R if present)
T (List Price)	PL
AC (Image URL)	ImageURL
AD (Tags)	TG

If the mapping is ambiguous, ask the user to confirm.

Manufacturer code lookup

Convert full brand names to standard 3-5 character codes:

Brand	MC Code	Brand	MC Code
Herman Miller	HMI	Blu Dot	BLU
MillerKnoll	MKN	Design Within Reach	DWR
Knoll	KNL	Fritz Hansen	FRH
Steelcase	STC	Vitra	VIT
Haworth	HAW	Arper	ARP
Teknion	TEK	Muuto	MUU
Humanscale	HUM	HAY	HAY
Kimball	KIM	Flos	FLS
National	NAT	Louis Poulsen	LPO
OFS	OFS	Artemide	ART
HBF	HBF	Restoration Hardware	RHB
Bernhardt	BRN	West Elm	WEL
Geiger	GEI	CB2	CB2

For unknown brands, use first 3-5 characters uppercased. Flag for the user to verify.

Step 4: Preview

Show a preview of the first 3 records before generating the file:

## SIF Preview (first 3 of 12 records)

Record 1:
  PN=670
  PD=Eames Lounge Chair and Ottoman
  MC=HMI
  MN=Herman Miller
  GC=Seating
  QT=3
  PL=5695.00
  WT=92
  TG=Executive Lounge
  OD=Santos Palisander / Black MCL Leather
  AN=DIM
  AD=32.75W x 32.5D x 33.5H in

...

12 records total. Generate SIF file? (y/n)

Step 5: Generate SIF File

Write the .sif file with CRLF line endings:

# Output path: same directory as input, or specified path
{input-dir}/{input-name}.sif

Step 6: Summary

✓ Generated ffe-schedule.sif
  Target: Standard (Hedberg/CAP/ProjectMatrix)
  12 records · 8 fields per record avg
  Manufacturers: HMI (5), KNL (3), STC (2), BLU (2)
  Total list value: $47,830.00
  Saved to: ~/Documents/project/ffe-schedule.sif

Pairs With

• /ffe-schedule — generate a schedule first, then convert to SIF
• /sif-to-csv — round-trip: CSV → SIF → send to dealer → receive updated SIF → back to CSV
• /product-spec-bulk-cleanup — clean up the CSV before converting
