What is the best way to merge multiple tabs with differently sourced data into a main table now that write to table is deprecated?

Quick Answer

Use Send table data to transfer rows from multiple tabs into your main table. Go to each source tab, click Actions → Send table data, select your main table as the destination, choose Send row, map the columns you want to transfer, and click Save. When you first send a row, it creates a new row in the destination table; subsequent sends update that same row. Note that data can only flow in one linear direction (A → B → C), and you can connect a maximum of 10 tables. [[clay.com](https://www.clay.com/university/guide/send-table-data])
