Free CSV tools
Quick fixes for the problems that stop a product file from importing. Free, no sign-up, and your files never leave your browser.
Quick fixes
CSV splitter
Split a large CSV into smaller files, each with the header row. Rows of the same product stay in the same file.
OpenRemove duplicate rows
Find and remove duplicate rows, either rows that are identical in every column or rows that share a value such as a SKU.
OpenFix CSV encoding
Turn garbled text like "Café" back into "Café", and convert the file to UTF-8, the encoding every store platform expects.
OpenFix barcodes
Excel drops leading zeros from barcodes and shows long ones as 1.23457E+11. This tool repairs what can be proven correct and flags what can't.
OpenExcel to CSV
Convert an .xlsx workbook to a UTF-8 CSV. Barcodes keep their digits, dates become YYYY-MM-DD, and accents survive.
OpenShopify handle generator
Turn product titles into clean Shopify URL handles, from a list of titles or for a whole product CSV.
