Convert Excel to CSV for Your Catalog

Updated 2026-08-24 · 8 min read

Excel is where catalogs usually start; CSV is where they need to end up for import. The conversion itself is one menu option, but the details — encoding, number formats, leading zeros — decide whether the import works. This guide covers the safe conversion path and what to do after the file is converted.

The basic conversion

  1. Open the workbook and select the sheet with the products.
  2. Choose File → Save As (Excel) or File → Download (Google Sheets).
  3. Pick CSV UTF-8 (Comma delimited) — not the plain CSV option, which can break special characters.
  4. Save. Only the active sheet converts — if your catalog spans multiple sheets, each must be converted separately.

What goes wrong in conversion

The conversion writes values as text. Three kinds of damage are common:

  • Leading zeros lost — SKU 00123 becomes 123 because Excel treated it as a number. Fix by formatting the SKU column as text before saving. This also applies to phone numbers, barcodes and anything else that starts with zero.
  • Numbers reformatted₹1,299.00 in Excel becomes 1299 or 1,299.00 depending on locale. Keep price columns plain numbers with two decimals, and remove currency symbols before saving.
  • Special characters garbled — accents and symbols break when the encoding is wrong. The UTF-8 option fixes this; the legacy CSV option causes it.
  • Formulas become values — usually what you want, but verify a few calculated cells after export.

From converted CSV to Hyperzod format

A clean Excel export is still an Excel-shaped CSV, not a Hyperzod-shaped one. The Hyperzod import expects PRODUCT.* columns and option groups; an Excel sheet with "Name, Price, Category" columns will not match.

This is where CSV Pilot fits. Upload the converted CSV into the tool, then either:

  • Edit it into shape — rename and map columns by describing the change, or
  • Regenerate it — paste the list into the chat and ask the agent to rebuild it as a Hyperzod catalog with the right columns, variants and validation.

The second path is usually faster: the agent maps your columns to the Hyperzod structure, adds missing required fields, and validates the result before export.

A quick checklist after converting

  • Correct sheet was active.
  • CSV UTF-8 option chosen.
  • SKU column formatted as text beforehand.
  • Prices contain plain numbers only.
  • Open the file in CSV Pilot's preview and confirm it parses correctly before importing into Hyperzod.

Why the round-trip is dangerous

The most common workflow is: export a CSV, open it in Excel to check it, re-save it — and break it. Excel quietly reformats values on open and save: SKUs lose leading zeros, dates get rewritten to your locale's format, long numbers become scientific notation. If you must inspect a CSV in Excel, treat it as read-only and keep a copy of the original. CSV Pilot's preview is a safer inspector: it parses the file as data, shows exactly what the importer will see, and never reformats your values.

Excel is for working; CSV is for exchanging. Convert carefully, then let CSV Pilot reshape the file into the structure Hyperzod expects.
