Use Cases

• Feeding data into scripts and databases

  Convert an Excel workbook into CSV so it can be imported by a database loader, ETL script, or command-line tool that expects plain text.

• Migrating spreadsheet data between systems

  Extract rows from a legacy Excel file to move contacts, inventory, or records into a system that only accepts CSV uploads.

• Preparing data for version control

  Turn a binary workbook into plain-text CSV so changes can be tracked and diffed cleanly in a git repository.

• Sharing tabular data across platforms

  Produce a universal CSV file from an Excel export so recipients on any operating system or app can open it without compatibility issues.

Examples

contacts.xlsx (Name, Email, Role)

Name,Email,Role
Ada Lovelace,ada@example.com,Engineer

Benefits

Best Practices

• Move the sheet you need to the first tab before converting.
• Match the delimiter to the tool that will import the CSV.

Common Mistakes
