Overview
Moving from Resource Management by Smartsheet to Microsoft Project is a flattening migration. Smartsheet organizes work hierarchically inside Sheets with Resource Management handling capacity and allocation across portfolios; Microsoft Project models a single project plan as a flat task list with Gantt scheduling, predecessor dependencies, and per-project resource pools. We extract projects and phases from the Resource Management API, collapse Smartsheet row groupings into task hierarchy, and assign resources with hours or percentage allocations back into Project's task-assignment model. Custom column types map to task-level custom fields with type metadata preserved. Automation rules and row-level attachments do not migrate; we deliver written inventories of both for the customer's project manager to rebuild manually. Time entries migrate as assignment-level work values where the source timer data is available before the one-week lock window closes.
Every standard and custom field arrives verified.

Object mapping
Each row shows how a Resource Management by Smartsheet object lands in Microsoft Project, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Resource Management by Smartsheet
Project (Sheet)
Microsoft Project
Project
1:1Each Smartsheet Sheet used as a project container maps to one Microsoft Project file (.mpp) or one Project for the Web project. We extract the sheet name as the project name, sheet-level metadata (created date, last modified) as project properties, and the sheet's column definitions as task fields. If the source account has multiple Sheets representing phases of a single program, we recommend consolidating into one Project with summary tasks per phase during scoping to avoid orphaned dependency chains.
Resource Management by Smartsheet
Row (Task)
Microsoft Project
Task
1:1Smartsheet rows map directly to Microsoft Project tasks. Row name becomes Task Name; Start Date and End Date columns map to Start and Finish in Project; Duration column maps to Duration. Row hierarchy (parent rows with indented sub-rows) becomes outline level in Project with summary tasks for parent rows and subtasks nested below. We preserve indent depth during transformation.
Resource Management by Smartsheet
Phase
Microsoft Project
Summary Task or Milestone
1:1Resource Management by Smartsheet Phases are a subclass of Project, which is a subclass of Assignable in the API hierarchy. We map Phase to a Project summary task with the phase name and no duration, containing all tasks assigned to that phase as subtasks. If the phase has a milestone marker in Smartsheet, we create a milestone task (zero duration) at the phase boundary. Phase ordering is preserved by sorting the resulting summary tasks in Project outline sequence.
Resource Management by Smartsheet
People (Resource)
Microsoft Project
Resource
1:1People objects from the Resource Management API (name, role, email, availability percentages) map to Microsoft Project Resources. We create a Resource Sheet entry per person with the name and Max Units from the availability field. Role information migrates to the Resource Initials or Resource Group field. If the source account uses placeholder resources (non-person entities), we create Material Resources in Project with the resource name and a zero-hour max units value.
Resource Management by Smartsheet
Assignment
Microsoft Project
Task Assignment
1:1Resource Management assignments link a person (resource) to a task (row) with allocation hours. We map these to Project task assignments with Assignment Work calculated from the allocation hours and the task duration. Assignment Owner and Assignment Phase from the API become task notes or custom fields. Resource peak allocation percentage in Smartsheet maps to Assignment Peak Units in Project.
Resource Management by Smartsheet
Custom Fields
Microsoft Project
Task Custom Fields
1:1Smartsheet custom column types (Text, Date, Contact List, Dropdown, Checkbox, Number, Duration) map to Project task custom fields. We use the custom field dialog in Project Professional or the Project for the Web API to pre-create custom fields matching the source column type before data import. Contact List columns create Text custom fields with the contact name as value since Project does not have a native person-link field at the task level.
Resource Management by Smartsheet
Dependency (Predecessor/Successor)
Microsoft Project
Task Dependency (Predecessor)
1:1Smartsheet row-level predecessor-successor relationships (exported via the dependency column) map to Project task predecessors with dependency type (Finish-to-Start by default). We validate that every predecessor task has been assigned an index before writing the predecessor link to prevent orphan references. Circular dependency detection runs post-transformation and flags any circular chains for the customer to resolve before production import.
Resource Management by Smartsheet
Time Entry
Microsoft Project
Assignment Work or Task Notes
lossyResource Management time entries contain hours logged against a specific task and user. We map these as Assignment Work values on the corresponding task-resource assignment in Project. Entries are only available for extraction if the migration is scoped before the seven-day timer lock window closes; we flag this prominently in the discovery checklist. If time entries are unavailable due to window expiry, we preserve entry metadata (total hours per task) as a task note for manual log.
Resource Management by Smartsheet
Portfolio
Microsoft Project
Multiple Projects or PWA Project Queue
many:1Resource Management Portfolios aggregate multiple projects with capacity and timeline summaries. Microsoft Project Desktop does not have a native portfolio object; multiple projects remain as separate .mpp files or separate Project for the Web projects. If the customer has Project Online with PWA (Project Plan 5 or Project Online Premium), we can submit projects to the Project Queue as a lightweight portfolio consolidation step. We do not replicate portfolio-level dashboards as these require a separate visualization layer outside Project.
Resource Management by Smartsheet
Report
Microsoft Project
Flat Data Export
1:1Smartsheet Reports aggregate data from one or more Sheets and export as CSV. We export report data as-is into a flat reference file delivered alongside the Project migration. Report structure (groupings, filters, formulas) does not migrate because Microsoft Project has no equivalent report aggregation object. We document each report's source sheets, filters, and computed columns as a written reference for the customer to rebuild in Power BI or Microsoft Project Web App reporting if needed.

Pair-specific challenges
Migration approach
Discovery and plan-tier verification
We audit the Resource Management by Smartsheet account to confirm plan tier (Pro vs Business/Enterprise) which determines whether we extract via API or CSV report. We inventory every project Sheet, phase hierarchy, custom column types, resource pool (People), assignment records, time entries (extracted before the seven-day lock window), and any automation rules present. We also identify attachments and grouped rows requiring manual handling. The discovery output is a written scope document with object counts, any data gaps, and an extraction method decision.
Data extraction from Resource Management API
For Business/Enterprise accounts, we authenticate to api.rm.smartsheet.com using OAuth 2.0 bearer token and paginate through the projects, phases, users, assignables, assignments, and time entries endpoints. We respect the 120 req/min rate limit with exponential backoff and the X-RateLimit-Reset header. For Pro-plan accounts, we extract via Smartsheet Reports CSV export with column-level mapping. We extract all time entries at this stage before the one-week lock window closes on any entries from the current week.
Schema design for Microsoft Project destination
We design the destination schema based on the target platform: Microsoft Project Desktop (.mpp) or Project for the Web (Microsoft 365). For Project Desktop, we define the task hierarchy (outline levels from row indent depth), custom fields (via Enterprise Custom Fields or local custom fields matching Smartsheet column types), resource sheet entries (from People data), and predecessor links (from Smartsheet dependency columns). For Project for the Web, we use the Microsoft Project Ruby SDK or direct REST API to create projects, add tasks, and assign resources. Phase consolidation recommendations are made at this step.
Transformation and test migration
We run a transformation pipeline that maps every Smartsheet row to a Project task with the correct start and finish dates, duration, outline level, custom field values, and predecessor links. Assignment work values are computed from the allocation hours. We run the test migration into a sandbox .mpp file (or Project for the Web test environment) and validate task count, date ranges, dependency chain integrity, and resource assignments. The customer reviews the test migration output against the source data and signs off before production migration proceeds.
Production migration and dependency validation
We run production migration with a data freeze window during cutover. Tasks import in outline order with parent tasks before child tasks to preserve hierarchy. Predecessor links write after all tasks are present to avoid orphan references. Resource assignments write after the resource sheet is populated. We generate a post-migration validation report comparing task counts, date ranges, and assignment totals between the Smartsheet source and the Microsoft Project destination and flag any discrepancies for the customer's PM to review.
Cutover handoff and automation inventory
We deliver the migrated .mpp files or a Project for the Web project export along with a written inventory of every Smartsheet automation rule, grouped row structure, and attachment file with their sheet location for manual rebuild. Time entry gaps (entries locked before extraction) are documented with task names and estimated hours for manual log. We do not rebuild automation rules in Microsoft Project; Power Automate is the replacement tool and requires separate configuration by the customer's admin or a Microsoft partner. We support a three-day hypercare window for reconciliation issues raised during the first week of live use.
