CSV problems and how to fix them

Each guide explains one common problem, how to fix it by hand, and has a working tool that runs in your browser.

• Shopify product CSV broken by quotes in titles
  A product title like 24" Monitor or an HTML description with quotes can shift a Shopify CSV into the wrong columns. Repair it in your browser without uploading the file.
• Fix unescaped double quotes in a CSV file
  CSV files break when a quote inside a field is not doubled. Here is why, how to fix it by hand, and a tool that repairs it in your browser.
• Fix garbled characters like é and ’ in a CSV
  When a UTF-8 file is read as Windows-1252, é becomes é and an apostrophe becomes ’. Repair it in your browser without uploading the file.
• Clean a CSV before a Salesforce or CRM import
  Unescaped quotes, garbled characters and uneven columns are common reasons a CRM import rejects rows. Repair the file in your browser first, without uploading it.
• Mask emails, phone numbers and card numbers in a CSV
  Hide personal details in a CSV before sharing it with a developer, a contractor or an AI tool. Masking runs in your browser; the file is not uploaded.
• Clean a confidential CSV without uploading it anywhere
  Repair quotes, fix garbled characters and mask personal details in a CSV entirely in your browser. The file is not sent to a server.
