Spreadsheet Data Cleaning & Validation - 28/03/2026 05:22 EDT

Budget: ₹100 - ₹400/hr

I have several Excel and Google Sheets files that must be cleaned and validated so they are ready for reliable analysis. The primary focus is on identifying and resolving missing values throughout the datasets.

I will provide the raw spreadsheets and clear notes on the desired rules for each column. Once you receive them, please inspect every sheet, locate any blanks or null-like placeholders, and apply the agreed treatment—whether that is intelligent imputation, flagging for manual review, or inserting default values.

Deliverables • A fully cleaned version of each spreadsheet with all missing values handled according to the guidelines • A brief change log (or summary sheet) showing what was fixed and how many cells were affected

The work is complete once the files open without errors, all previously empty cells follow the new standards, and the summary log reconciles with the source data row count.
