Key Features of Merge & Split Columns

Flexible Joining Delimiters: Merge fields together with spacing, dashes, commas, or custom character strings.
Custom Column Splits: Split column names (e.g. Full Name ➔ First Name, Last Name) based on delimiters.
Excel & CSV Compatibility: Seamlessly load local spreadsheets and export restructuring summaries client-side.
Privacy First Design: No server connections. All spreadsheet unparsing and array mapping happens entirely in your browser.
