Question details

The user needs to extract daily working hours associated with specific project IDs from a dataset and calculate the total accumulated hours per project on a separate summary worksheet.

Product: Excel
Device & OS: not provided
Scenario: Tracking employee productivity by aggregating daily hours logged against specific project identifiers mixed within text or spanning multiple rows.
Observed behavior: The goal is to automatically calculate total hours per project by extracting numeric hour values associated with a project ID and outputting the sum on a secondary sheet.

Before you start

Ensure your raw data is consistently formatted and that you know exactly how the project IDs and hours are entered (e.g., in separate columns or combined in a single string) before applying extraction formulas.

Solution 1Recommended

Use the SUM and TEXTAFTER Formula

Best for modern versions of Excel where you need to extract hour values directly following a specific project identifier string within a cell.

If your hours are recorded in a cell immediately following a project ID, the TEXTAFTER function can isolate the numeric value so the SUM function can add it up. Note that TEXTAFTER is available in Microsoft 365 and newer Excel versions.

Set up the summary sheet

Create a separate summary worksheet and list your unique project IDs in a dedicated column (for example, cell D8).

Enter the extraction formula

Select the cell where you want the total hours to appear and enter the formula: =SUM(--TEXTAFTER(A2:A7,D8,,,,0))

Adjust references

Modify the range 'A2:A7' to match the location of your raw data, and 'D8' to match the cell containing the specific project identifier you are summarizing.

Calculate the result

Press Enter to calculate the total summarized hours for that specific project. Drag the fill handle down to apply it to other projects in your summary sheet.

Double Negative Operator: The double negative (--) before TEXTAFTER is used to convert the extracted text string back into a numeric value so that the SUM function can calculate it.

Solution 2

Use the SUBSTITUTE Array Formula

A robust alternative for older versions of Excel that do not support the TEXTAFTER function.

Solution 3

Structure Data for Standard SUMIF

The cleanest and most scalable method is to organize your source data into distinct columns so you can use standard conditional math functions.

Frequently Asked Questions

Can I use a Pivot Table to summarize employee hours instead of formulas?

Yes. If your data is cleanly organized into separate columns for 'Project ID' and 'Hours', simply highlight your data, go to Insert > Pivot Table, and drag 'Project ID' to the Rows area and 'Hours' to the Values area to instantly summarize totals.

Why is my TEXTAFTER formula returning a #NAME? error?

The TEXTAFTER function is only available in Microsoft 365 and modern versions of Excel. If you receive a #NAME? error, your software version does not support this function, and you should use the SUBSTITUTE and ISNUMBER formula alternative provided in Solution 2.

How do I summarize hours when data is split across multiple daily worksheets?

You can use a 3D reference in your formula, such as =SUM(Monday:Friday!C2) if the project total is in the exact same cell on every sheet, or combine multiple SUMIF functions to aggregate data from different sheets into a master summary.

What if my project ID and hours are combined in the same cell?

If data like 'ProjA-8hrs' is contained in a single cell, standard SUM functions will not work. You must use text extraction formulas like TEXTAFTER, or a combination of MID, FIND, and VALUE to separate the numeric hour value before it can be mathematically calculated.
