Every row keeps its origin
The workbook can show where a row came from, which file created it, and what original columns were carried forward.

Audit and accounting in Excel
Use Clark for audit and accounting beside your existing workbook. Prepare reconciliations and workpapers, extract data, and trace figures to their sources. Audit teams can also sample and test evidence.
The December balance ties. The bank statement closing balance of $1,482,660.14 agrees to the trial balance cash account with no unreconciled difference.
Extraction, sampling, testing
Audit and accounting teams can keep the formulas, schedules, and workbook structure they already use while Clark adds workflow context around the sheet. For audit testing, the sequence is Extract, Sample, and Test. Chat sits beside that sequence so teams can ask questions, explain exceptions, and move work forward without turning the assistant into a separate audit step.
One audit workflow
These are the three steps in the Excel add-in workflow. Chat is available alongside them as the assistant layer: it helps explain what changed, find support, answer questions, and move between steps.

What stays connected
Instead of adding another place to manage, Clark keeps the supporting record close to the workbook: source, decisions, sample basis, evidence, and review context all remain attached to the work your team is doing.
The workbook can show where a row came from, which file created it, and what original columns were carried forward.
Missing keys, excluded rows, outliers, and cleanup decisions remain attached to the population instead of disappearing into notes.
Sample size, population, exclusions, and seed are preserved so reviewers can understand and repeat the selection.
Support, testing attributes, conclusions, and review comments stay connected to the row they explain.
