Bulk-importing an Excel catalog into your online store (2026)

The verdict in three sentences

Adding hundreds of products one by one is a launch killer: budget 3 to 4 days of typing. The 2026 method is a clean CSV template plus a mapped import that loads 500 SKUs in under an hour, with row-by-row validation. Bonus: to change 200 prices, you re-import the same file instead of retyping everything.

The file template that passes first time

Imports almost always fail on fuzzy columns. Lock a template with required columns and validation rules.

ColumnRequiredValidation rule
nametext, not empty
skuunique, no spaces
priceinteger FCFA
stockinteger >= 0
categoryexists or created
variantnosize/color
image_urlnovalid https link
descriptionnofree text

Key rules: unique SKU (duplicates rejected), numeric price with no "FCFA" or spaces, positive integer stock. A pre-filled template with 2 example rows avoids 80 % of errors.

The flow: we map your Excel columns to store fields, validate in a dry run, the system flags each faulty row with its reason, you fix, then run the final import. Images load in bulk via URL or a ZIP archive.

Mini case study

Fatou, who runs a fine-grocery store in Dakar, launches with 480 SKUs in Excel. By hand at ~40 products/hour, she'd need ~12 hours over 3 days, with guaranteed typos. With the CSV template and mapped import she loads everything in 35 minutes, fixes 12 flagged rows, and publishes the same day. Savings: ~11 hours, roughly 3 days of launch delay avoided — and every delayed day is revenue not collected.

FAQ

What file format do I need? A UTF-8 CSV (exported from Excel or Google Sheets). We provide a template with required columns and two example rows to copy.

How are duplicates handled? Detection is on the SKU: any row with an existing SKU is flagged in the report and nothing is overwritten without your consent.

What if a row has an error? The dry-run import lists each faulty row with the reason (non-numeric price, unknown category, broken image). You fix and rerun; valid rows go through.

Can I update prices later? Yes, that's one of the big wins. You edit the price column in the same file and re-import: 200 prices updated in 5 minutes instead of a day of clicking.

Are images imported too? Yes, via an https URL in the image_url column, or a ZIP archive named by SKU. No more uploading each photo by hand.
