Spreadsheet checks before running Damages Allocation in Massachusetts

What the checker catches
Before you run Damages Allocation in Massachusetts with DocketMath, you can prevent a surprising number of downstream allocation errors by running spreadsheet checks first. The goal isn’t to “optimize” your numbers—it’s to catch mismatches that create incorrect results, especially when you’re working off exports, formulas, or mixed date formats.
Here are the most common issues a spreadsheet-checker flow is designed to catch before you run damages-allocation in US-MA:
Statute-of-limitations (SOL) filtering mistakes
- Missing or incorrectly formatted date of accrual (or the closest equivalent you’re using).
- Using the wrong date column (for example, invoice date instead of the event/accrual date).
- Off-by-one errors caused by inconsistent time zones or Excel date serial conversions.
Row-level alignment problems
- One damages line item isn’t aligned to the correct category, time period, or claimant/entity row.
- Units don’t match (for example, hours vs. days; dollars vs. cents) due to formatting and formula inheritance.
Arithmetic integrity issues
- Columns that sum visually but don’t reconcile (for example, a subtotal referencing the wrong range).
- Negative values where your allocation logic expects non-negative inputs—unless you intentionally model credits.
Inconsistent naming conventions
- Category names differ across tabs (for example, “Overtime” vs. “Over time”), causing silent misgrouping.
- Duplicate categories that look identical but differ by trailing spaces or capitalization.
Allocation-driving fields missing or mismatched
- Missing allocation basis values (such as weights, share percentages, or qualifying period amounts—depending on your worksheet design).
- Percentages that don’t add to 1.00 (or don’t meet your internal tolerance), which can skew how totals distribute.
Warning: A spreadsheet can “look right” while still feeding DocketMath bad structure—particularly if formulas reference shifting row numbers or if dates are stored as text. When that happens, the allocation output can be wrong in ways that are hard to detect after the run.
The Massachusetts SOL context the checker uses (US-MA)
DocketMath’s US-MA checker uses a general/default SOL period of 6 years, based on:
- Mass. Gen. Laws ch. 277, § 63
No claim-type-specific sub-rule was identified in the provided jurisdiction data. The checker therefore treats this as the default period rather than branching into specialized timelines by claim type.
Practical takeaway: before allocating damages, verify that any date used to determine “within 6 years” is consistent across your sheet—and consistent with the date meaning you chose in your workbook.
When to run it
Run the checker right before you commit data to an allocation calculation, and then again after each major edit batch. This cadence helps catch both “bad imports” and “bad changes” that otherwise propagate into allocation outputs.
A practical workflow:
After you import or paste data
- Normalize columns (dates, numbers, identifiers).
- Run the checker to validate structure and arithmetic.
After you edit date logic or category mappings
- If you changed how the accrual/trigger date is derived, rerun.
- If you remapped categories, rerun.
Before exporting or finalizing the allocation run
- Treat checker results like a preflight step.
- If there are failures, fix inputs first—don’t try to “paper over” errors by adjusting outputs.
After you copy the sheet to a new template version
- Excel copies can break absolute/relative references.
- Rerun to confirm ranges still match what the logic expects.

Before you run it, review your spreadsheet inputs and confirm they align with the checks below. Even experienced teams typically see the most issues here.
Input sanity checks (what changes when you fix them)
| Spreadsheet issue | What you’ll typically see after fixing it | Why it matters for allocation |
|---|---|---|
| Accrual date is text | Checker flags date parsing; allocation output changes | SOL window gating can exclude/include rows incorrectly |
| Wrong date column selected | Checker warns about unexpected date ranges | Damages can be categorized into the wrong time buckets |
| Percentages don’t sum to 1.00 | Checker indicates distribution issues | Allocations redistribute across categories |
| Category labels differ slightly | Checker shows unmatched/missing categories | Items get grouped incorrectly or dropped from splits |
| Subtotal references wrong range | Checker finds reconciliation failures | Totals can “look right” but misdrive allocation basis |
Massachusetts-specific reminder (US-MA)
If your sheet uses “within SOL” filtering, the checker applies the general 6-year period from Mass. Gen. Laws ch. 277, § 63. Because the jurisdiction data did not identify claim-type-specific sub-rules, it will not switch timelines based on claim labels.
Pitfall: If your workbook includes multiple “date concepts” (invoice date, service date, payment date, accrual date), mixing them can quietly change which rows fall inside the 6-year lookback—changing totals you later allocate.
Gentle note on scope
This checker is designed to validate spreadsheet integrity and consistency before calculation. It doesn’t replace legal evaluation of accrual or eligibility of claims. Use it as a data quality gate for your Massachusetts allocation workflow.
