Common Errors with LibreOffice Calc and How to Fix Them
1) Numbers Are Displayed as Text
Symptoms: Calculations do not work even if the values seem correct. Cause: The cells are in the wrong format (Text instead of Number). Solution:
- Select the affected area
- Go to Format > Cells > Number
- Press Ctrl + Shift + Y to force conversion if necessary
2) Decimal Separator Not Recognized
Symptoms: Calc rejects numbers with commas or periods depending on the language. Cause: The regional settings do not match the expected format. Solution:
- Go to Tools > Options > Language Settings
- Check Locale Language
- Select French (France) for commas or English (US) for periods
3) VLOOKUP Formula Returns Nothing
Symptoms: The formula shows an error or a blank result. Possible Causes:
- The first column is not sorted
- The sought value has hidden spaces Solution:
- Use FALSE as the last argument:
=VLOOKUP(A2,A1:B50,2,FALSE) - Remove spaces with:
=TRIM(A1)
4) Columns Mismatch When Opening an Excel File
Symptoms: The file opens, but the layout is messy. Cause: Excel styles are not always consistent in Calc. Solution:
- Select all (Ctrl + A)
- Apply a Normalized Cell Style: Styles > Default
5) Calc Becomes Slow with a Large File
Symptoms: Scrolling or calculations take time. Causes: Too many formats, too many formulas, or too many imported rows. Solutions:
- Remove unnecessary formatting: Format > Clear Direct Formatting
- Convert repeated formulas to fixed values if possible
- Use a Pivot Table to reduce the visible size
6) The Chart Does Not Reflect New Data
Symptoms: The chart remains unchanged even if the table changes. Cause: The data range is not dynamic. Solution:
- Double-click on the chart
- Click on Data > Data Range
- Adjust the range manually
