Converting daily data to monthly data in Excel can streamline your analysis and reporting process, providing a clearer view of trends and patterns over time. This transformation is crucial for various professionals who deal with time series data, such as financial analysts, marketers, and data scientists.

To convert daily data into monthly data without helper columns, use array formulas with functions like MIN, IF, and TEXT. Input an array formula with CTRL+SHIFT+ENTER to process multiple cells simultaneously. This method skips additional helper data, streamlining the conversion process.
Utilize the DAY function to exclude weekends from your data. For holidays, the WORKDAY function is effective in filtering out specific non-working days. These functions refine the dataset, ensuring accurate monthly aggregation.
Implement a helper column to determine the first day of each month. Apply an array formula with MIN, IF, and TEXT functions to facilitate aggregation. Then, employ Excel's Home > Sort & Filter > Filter feature to display only the first days. Copy the filtered results to a new sheet to finalize the monthly dataset.
Pivot tables in Excel, such as in Excel 2011 for Mac, offer a straightforward approach to group daily data into monthly summaries. Add your data to a pivot table and use its grouping function to consolidate by month or year, summing up data as required.
