Connectors Microsoft Excel files

Microsoft Excel files data integration with Lima, in both directions.

Planning parameters, forecast overrides and price lists still live in Excel in most companies. Lima reads workbooks by sheet and named range, applies header and type rules, and turns each row into a governed record with an owner, so a spreadsheet becomes a controlled input to a planning load.

How Lima reads and writes Microsoft Excel files

Method by method.

Each method has a job. The first load uses the bulk method; the daily run uses the incremental or change-capture method; write-back uses the interface the system itself uses.

MethodWhat it doesWhen it is used
Sheet and range readsReads named sheets and ranges with header rows.Parameters and overrides.
ValidationTypes, ranges and reference checks; bad rows become exceptions.Every load.
Workbook writesProduces Excel for people to review.Outbound.
What it covers

Objects and patterns.

The objects are the tables, views or records Lima reaches through the methods above. The patterns say how a copy is made and kept current.

Prerequisites, then four steps.

The prerequisites are what the team that runs Microsoft Excel files grants. The four steps are the same for every connector.

  • A file location
  • Header row and sheet names agreed
  • An owner per workbook
Register the connectionEndpoint, credentials from the vault, and the method. The connection is tested and a failed test names the cause.
Choose the objects and the patternPick tables or objects from the discovered schema, and the pattern: full, incremental, change capture or streaming.
Run the first load with checks onEvery row is valid or becomes an exception with an owner. The run ends with a count and a control total per table.
Schedule it on the business calendarA run window with a deadline; pause, resume and replay if a check trips; the report after every run.
What happens to a bad record

Incoming data = valid records + exception records. A row that fails a check is kept, routed to the person who owns it with a deadline, and replayed once fixed. The load carries on with the valid rows and the report says exactly what was held back. How exceptions work →

Plain meanings.

ConnectorA packaged way to read or write one kind of system, with its authentication, methods and prerequisites described.
Full, incremental, change capture, streamingFour ways to make and keep a copy: read everything; read what changed since last time; read changes from a log as they happen; consume events in small batches.
Write-backWriting a result into the system that owns it through its released interface; the system's response is the confirmation.
Control totalThe sum of a key amount column compared between source and target, along with the row count, at the end of a run.
Exception recordA row that failed a check: kept, routed to an owner, replayed once fixed.
Questions

Asked about this connector.

Does Lima install anything in Microsoft Excel files?

Lima connects from outside through the interfaces listed above with credentials your administrators grant. Where a vendor requires its own agent or add-on for a method, the prerequisites say so.

How is load on Microsoft Excel files kept in check?

Parallel reads are capped and the cap is agreed with the team that runs the system. Large reads run inside an agreed run window. Change capture keeps the daily volume small.

What do we see when a run finishes?

A report per run: rows in, rows out, control totals and variance per table, the exceptions held back and who owns them, and whether the deadline was met.

Can we start small?

Yes. Most estates start with one source, one target and one dataset, then add tables and patterns on the same connection.

A trial connects this system, runs a first load and ends with a reconciliation report. Your administrators see the prerequisites before anything is installed.
