ctx.thisRow provides convenient methods to read and write data on the currently executing row. This is the most common way to interact with your data within column formulas.
ctx.thisRow is not available in webhook columns, as there is no “current
row” context during webhook execution.
For foreign key columns, use the referenced sheet name instead of the column name, and use dot notation to access fields on the related record:
// If "company_id" is a foreign key to the "Companies" sheetconst companyName = ctx.thisRow.get("Companies.name");const companyWebsite = ctx.thisRow.get("Companies.website");// You can chain through multiple relationshipsconst ownerEmail = ctx.thisRow.get("Companies.Owner.email");
