Useful next steps
Working with csv join
Spreadsheet tasks involve values, formulas, data types and presentation. A conversion may preserve the displayed value without preserving the formula that produced it. Identifiers, dates and locale-specific decimal separators deserve special attention.
Common questions
Why do identifiers lose leading zeros?
A spreadsheet can interpret a text identifier as a number. Once 00123 is treated as 123, formatting may be needed to display zeros again. Preserve the original value as text when its exact representation matters.
Does CSV keep formulas and multiple sheets?
CSV represents one flat table. It does not retain a workbook’s sheets, formatting or full formula behavior. Treat it as an exchange format for values and review how the receiving application interprets them.
