What Identity Worksheets Actually Are
Identity Worksheets are structured data sheets used to map, verify, and manage user identities across systems. They typically contain fields for unique identifiers, authentication methods, role assignments, and audit timestamps. Most teams use them during onboarding, access reviews, or compliance audits. I first encountered Identity Worksheets when migrating a legacy SSO system to a cloud-based identity provider. The migration involved roughly 4,200 user records spread across seven different authentication sources. Our team built a master Identity Worksheets spreadsheet that linked each user's legacy employee ID to their new UUID, mapped their group memberships, and flagged any accounts with conflicting email addresses. We spent about three weeks cleaning the source data before we could even start the actual migration. The basic process goes like this: you export raw identity data from each source system, normalize the fields into a standard schema, cross-reference everything to catch duplicates or conflicts, then import the cleaned dataset into your target system. The trickiest part is normalization because every source system does naming conventions differently. Active Directory uses sAMAccountName, Okta uses email, and our old HR system used a nine-digit numeric ID that predated everything else.
A Problem I Ran Into That No One Warned Me About
During that same migration, I discovered about sixty accounts where the employee's legal name in the HR system didn't match the name they used in Slack and GitHub. These weren't typos. People had changed their names legally but never updated certain systems. The Identity Worksheets caught the mismatches during the normalization phase, but resolving them was messy. I couldn't just overwrite one system with another because there was no single source of truth for display names versus legal names. My workaround was to create a split field in the Identity Worksheets. I added a column for "legal identifier" and another for "preferred display name." Then I wrote a script that pulled the legal name from HR and the preferred name from the collaboration tools, merged them, and flagged any records where the mismatch exceeded a character threshold. That threshold approach caught about twelve accounts that the basic comparison missed because someone had added a middle initial or a hyphen somewhere along the way.
Fields You Should Include in Your Identity Worksheets
A minimal Identity Worksheets template should have at least these columns: source_system, original_id, normalized_email, legal_name, display_name, role_group, department, hire_date, termination_status, last_audit_date, and conflict_flag. You don't need all of these for every use case but dropping the audit fields turns Identity Worksheets into just another spreadsheet nobody checks. More advanced setups add hash values for deduplication and a confidence_score column that tracks how sure the system is that a record is accurate. I've seen teams use fuzzy matching algorithms on the email and name fields to auto-populate that score. It cuts down manual review time significantly, usually from about four hours per batch down to roughly forty-five minutes depending on data quality going in.

Where Identity Worksheets Fall Apart
Let me be straightforward about the limitations. Identity Worksheets work well when your identity ecosystem is relatively static. If you're in an environment with high contractor turnover, frequent role changes, or automated provisioning through APIs, spreadsheets become a liability. The data ages the moment you save it. I've seen companies lose whole weekends trying to reconcile Identity Worksheets against live directories only to realize the source exports were twenty-four hours stale. Another issue is that Identity Worksheets don't handle hierarchical relationships natively. If you need to model manager-to-report chains or nested security groups, you end up adding join tables or cross-references that make the sheet unwieldy fast. At around two thousand rows, most people I know stop using spreadsheets and move to a proper relational database or a purpose-built identity governance tool like Saviynt or SailPoint. The per-seat cost of those tools is real, but the alternative is someone spending thirty hours a week maintaining a Google Sheet.
Getting Started Without Overcomplicating It
If you're building your first set of Identity Worksheets, start small. Pick one source system and one target system. Export fifty records, normalize them by hand, and document every mapping decision. Those decisions matter later when someone asks why a contractor got access to a production database. Keep a change log column in the sheet itself. It sounds basic but I've audited projects where the Identity Worksheets contained no history of who changed what and when. For a download template, look for CSV or XLSX files that include the column structure I outlined above. Many IAM blogs and GitHub repositories have shared samples. Search for "identity worksheets csv template" and you'll find several options. Just remember to adapt them to your own field names and compliance requirements rather than importing them blindly.
