/sif-to-csv — SIF to CSV Converter

Converts a SIF (Standard Interchange Format) file from a dealer or procurement system into a clean, human-readable CSV or Google Sheet. Translates field codes to column headers, expands options and attributes, calculates pricing, and computes totals.

When to Use

• Received a SIF file from a dealer and need to review it as a spreadsheet
• Importing dealer pricing back into your FF&E schedule
• Comparing a dealer quote (SIF) against your original specification
• Loading dealer data into the master Google Sheet

SIF Format Reference

SIF is a text-based key-value format. Each line is CODE=VALUE, terminated by CRLF. Products are separated by records starting with PN=.

Core fields

Code	Name	Description
SF	Specification File	Project reference (header)
ST	Specification Title	Display title (header)
PN	Product Number	SKU — starts a new record
PD	Product Description	Product name
MC	Manufacturer Code	3-5 char code
MN	Manufacturer Name	Full name
QT	Quantity	Integer
NT	Quantity (alt)	Some systems use NT instead of QT
GC	Category / Group Code	Product category
G0	Vendor / Group ID	Vendor identifier

Pricing fields

Code	Name	Description
PL	List Price	Unit list price
P1-P5	Price Tiers	Alternate price tiers
I1	Unit List Price (Cyncly)	Cyncly Worksheet
I2	Purchase Price (Cyncly)	Cyncly Worksheet
S- / S%	Sell Discount %	Sell = PL - (PL × S- × 0.01)
P% / B%	Purchase/Buy %	Cost = PL × (P% × 0.01)

Product detail fields

Code	Name	Description
TG	Side Mark / Tag	Room, area, or project tag
ON / OD	Option	Number + description pair
AN / AD	Attribute	Number + description pair
WT	Weight	Product weight
VO	Volume	Product volume
PRC	Product Category (Cyncly)	Cyncly category

Link fields

Code	Name	Description
ProductURL	Product Page URL	Link to product page
ImageURL	Product Image URL	Link to product image
PV	Picture Path	Local file path

CET	EC	Manufacturer code (alt)

Step 1: Accept Input

SIF file:

/sif-to-csv ~/Documents/project/dealer-quote.sif

Pasted SIF content:

/sif-to-csv
SF=Project Alpha
ST=Dealer Quote - March 2026
PN=670
PD=Eames Lounge Chair and Ottoman
MC=HMI
QT=3
PL=5695.00
S-=42
TG=Executive Lounge
OD=Santos Palisander / Black MCL Leather

Step 2: Parse SIF

Read the file and parse each record:

1. Header fields: Extract SF and ST
2. Records: Split on PN= boundaries
3. For each record, extract all fields
4. Detect manufacturer code variant: look for MC, MG, or EC — normalize to brand name
5. Detect price variant: look for PL, P1, I1 — use whichever is present
6. Detect quantity variant: look for QT or NT
7. Calculate derived values:
   • Sell Price: PL - (PL × S- × 0.01) if discount present
   • Net Price: PL × (P% × 0.01) if purchase % present
   • Extended List: PL × QT
   • Extended Sell: Sell Price × QT

For unknown codes, keep as-is and flag.

Options and attributes

• Multiple ON/OD pairs → concatenate into "Options" column, separated by |
• Multiple AN/AD pairs → concatenate into "Attributes" column, separated by |
• If AN=DIM, parse dimension string back into W/D/H if possible

CSV file

Save as {input-name}-parsed.csv:

Item #, SKU, Product, Brand, Qty, List Price, Discount %, Sell Price, Ext List, Ext Sell, Category, Weight, Options, Attributes, Tag, Product URL, Image URL, MC Code

Google Sheet (master schema)

Write to the 33-column schema (defined in ../../schema/product-schema.md, CRUD patterns in ../../schema/sheet-conventions.md):

• Column A (Link) ← ProductURL
• Column C (Product Name) ← PD
• Column E (SKU) ← PN
• Column F (Brand) ← MC expanded
• Column J (Category) ← GC or PRC
• Column K-O (Dims) ← parsed from AD where AN=DIM
• Column P (Weight) ← WT
• Column T (List Price) ← PL/P1/I1
• Column U (Sale Price) ← calculated sell price
• Column S (Selected Finish) ← OD
• Column AC (Image URL) ← ImageURL
• Column AD (Tags) ← TG
• Column AE (Notes) ← "From SIF: {ST}. Discount: {S-}%. Qty: {QT} · Ext: ${ext_sell}"
• Column AF (Status) ← "quoted"
