Data Tally Workflow – Sundar Mishra (My Work Secret)
Step 0: Data Import & Backup
-
Always save a raw copy before starting.
-
Document source details: file name, report name, extraction date, etc.
Step 1: Data Cleaning & Validation
Clean and standardize the dataset without altering its meaning.
🔧 Common Cleaning Formulas:
-
TRIM()
→ Remove unwanted spaces. -
CLEAN()
→ Remove non-printable characters. -
UPPER()
,LOWER()
,PROPER()
→ Standardize text case. -
TEXT()
→ Format values (e.g., dates, numbers). -
VALUE()
→ Convert text numbers to numeric format. -
DATEVALUE()
→ Convert text dates to real dates. -
ROUND()
,ROUNDUP()
,ROUNDDOWN()
→ Ensure consistent decimal places. -
ISNUMBER()
,ISTEXT()
,ISERROR()
→ Validate data type.
🔑 Checks:
-
Totals before & after cleaning must match (
SUM()
check). -
Define correct data types: Date, Number, Text.
Step 2: Understanding Data & Setting Goal
-
Verify data source and reliability.
-
Identify data pattern (repeated fields, keys, categories).
-
Define goal of tally (e.g., reconciling totals, validating balances).
-
If needed, ask senior/AI tools how to solve, not to do it for you.
🔧 Helpful Formulas for Exploration:
-
COUNT()
,COUNTA()
,COUNTBLANK()
→ Count records. -
UNIQUE()
→ Identify unique values (Excel 365+). -
SORT()
/SORTBY()
→ Detect ordering & patterns. -
LEN()
→ Spot inconsistent text lengths (e.g., ID codes).
Step 3: Tallying & Multi-way Verification
Perform tally and check in more than one way.
🔧 Core Tally / Verification Formulas:
-
SUM()
→ Total values. -
SUBTOTAL()
→ Dynamic totals (ignores hidden rows). -
SUMIFS()
→ Conditional summing. -
COUNTIFS()
→ Conditional counting. -
VLOOKUP()
,HLOOKUP()
→ Compare values across reports. -
INDEX() + MATCH()
→ Flexible lookups. -
XLOOKUP()
(if available) → Modern lookup alternative. -
IF()
/IFS()
→ Conditional checks. -
IFERROR()
→ Handle mismatches gracefully. -
EXACT()
→ Compare two text fields exactly. -
TEXTJOIN()
→ Concatenate multiple fields for pattern matching.
🔑 Cross-verification techniques:
-
Totals vs. subtotals (
SUMIFS()
vs.SUM()
check). -
Record-level check (
VLOOKUP()
/XLOOKUP()
). -
Duplicate detection (
COUNTIFS()
> 1). -
Mismatch highlighting (conditional formatting with formulas).
Step 4: Finalization & Reporting
-
Confirm data is error-free and consistent.
-
Prepare summary output (Excel Pivot, PDF, or Dashboard).
🔧 Useful Reporting Tools:
-
Pivot Table (with
SUM
,COUNT
, % of Total). -
Charts for visualization.
-
TEXT()
with custom formats for clean report presentation.
📌 Final Principle: Data is finalized only if multiple methods confirm the same result.
✅ End Result: Cleaned, reliable, and thoroughly verified data ready for reporting, auditing, or deeper analysis.
