How-to Guide

1. Enter the LEFTB function

Entry path: Formulas tab → formula bar

1. Open WPS Spreadsheet and select the cell where you want the result to appear.
2. Type = in the cell or formula bar.
3. Continue by typing LEFTB(.
4. Check whether the function name and parameter prompt appear.

Success Criteria

• Interface result: the cell enters formula editing mode and shows LEFTB-related prompts.
• Next action available: you can continue entering parameters and complete the formula.

Tips While Using

• Common mistake: if you do not start with =, the content is treated as plain text.
• Environment note: this action must be performed in an editable worksheet cell.

2. Fill in parameters with syntax prompts

Entry path: formula bar → LEFTB parameter input

1. After LEFTB(, enter the text value or cell reference to process.
2. Add the parameter separator, then enter the number of bytes to return.
3. Check that the closing parenthesis is complete.
4. Press Enter to confirm the formula.

Success Criteria

• Interface result: the cell displays the calculated result.
• Next action available: when you select the cell again, the full formula is visible in the formula bar.

Tips While Using

• Common mistake: unmatched parentheses, missing separators, or incorrect parameter counts can cause an error.
• Environment note: byte length can vary depending on the text content, so verify the returned result against your actual data.

3. Use LEFTB with cross-sheet references

Entry path: formula bar → worksheet reference

1. Select the target cell and type =LEFTB(.
2. Switch to the worksheet that contains the source data.
3. Select the source cell to complete the reference.
4. Enter the return byte count and press Enter.

Success Criteria

• Interface result: the result cell returns the specified left-side bytes from the referenced text.
• Next action available: when the source sheet data changes, the result updates accordingly.

Tips While Using

• Common mistake: referencing the wrong sheet or cell can produce an unexpected result.
• Environment note: make sure the referenced worksheet data is accessible and valid.

4. Combine LEFTB with other functions

Entry path: formula bar → nested formula editing

1. Enter a formula structure that includes LEFTB in the target cell.
2. Use LEFTB as an argument inside another function, or use another function result inside LEFTB.
3. Check the order of parameters and all parentheses.
4. Press Enter to finish the calculation.

Success Criteria

• Interface result: the cell returns the final result of the combined formula.
• Next action available: changing related parameters or referenced data triggers recalculation.

Tips While Using

• Common mistake: nested formulas often fail because of missing parentheses or incorrect argument order.
• Environment note: editing longer formulas in the formula bar makes the structure easier to review.
