The Scenario
Your team's senior backend engineer left last quarter. The Prisma schema file in the repo is two months behind — migrations ran in staging that never made it into a commit. Now you have a new contractor starting Monday who needs to understand the database structure, and the repo is not the ground truth anymore.
Your manager has asked you to produce an authoritative schema reference in Excel by Friday so the contractor can onboard without bugging the remaining engineers all week.
The bad version:
- Connect to each database via psql, run describe for each table
- Copy the output from each describe block, paste into an Excel sheet
- Reformat manually — psql describe output is not a clean table, column types include formatting characters, constraints are on separate lines
- Do this across all 15 tables in 3 databases, one at a time
Two hours of work before you have written a single word of documentation. And the moment another migration runs, the sheet is stale.
The Easy Way: One Prompt in SheetXAI
SheetXAI is an AI agent that lives inside your Excel workbook. It reads the workbook, and through its Prisma integration it can inspect your database schema and write the complete structure — tables, columns, types, constraints, foreign keys — into your cells without a single psql command.
Open a blank schema reference workbook and try:
Inspect the schema of my Prisma database for project [ID] and create a sheet listing every table, column name, data type, nullable flag, and any constraints or foreign key references
What You Get
- One row per column across all tables
- Columns: table name, column name, data type, nullable (yes/no), primary key (yes/no), foreign key reference if present
- Tables grouped so the sheet reads table by table rather than scattered
- Constraint and foreign key notes as plain descriptions, not raw SQL syntax fragments
What If the Data Is Not Quite Ready
I need each of the 3 databases on a separate Excel worksheet
Pull the full schema from all 3 Prisma databases listed in column A and write one Excel worksheet per database, each with columns: table, column, type, nullable, primary key, foreign key
I want indexes included in the reference
Inspect the schema of my Prisma database for project [ID], list every table and column with type, nullable, and primary key, and in a second pass add a column showing any indexes defined on each column
I want to highlight columns that will reject null inserts with no default
Inspect the full schema of my Prisma database for project [ID], write all columns to this sheet, and in column G mark "insert-required" for any column that is NOT nullable and has no default value defined
Pull the schema, flag foreign keys, and write a plain-English description of each table in one shot
Inspect my Prisma database schema for project [ID], write the full column list to this sheet, in column H note foreign key references as "references [table].[column]", and in column I write a one-sentence description of what each table appears to store based on the column names
The pattern: combine the schema pull, the annotation, and the plain-English interpretation in one prompt so the contractor has a usable reference from day one.
