SPLICE SCHEMA_MERGER_V1
Drop two Excel or CSV files with different schemas. Splice auto-suggests column matches, lets you configure transforms (date formats, split, combine, lookup tables, custom formulas, constants), draws visual connector lines between matched fields, and exports a merged file. It also generates the equivalent Python script so you can re-run the mapping headless anytime. Entirely client-side. No data leaves your browser.
Auto-Match Columns
Splice compares column names across both files and suggests matches ranked by similarity. Accept the good ones, fix the edge cases.
Seven Transform Types
Direct copy, date reformat, split by delimiter, combine columns, lookup tables, custom JavaScript formulas, and constant values. Covers every real-world mapping.
Python Export
Every visual mapping generates a reusable Python script. Run the same merge headless on a schedule or in a pipeline.
