Why convert TSV to ACCDB?
A TSV file is flat read-only text with no indexes, relationships, or data-type enforcement. Importing it into an .accdb table lets you query it with SQL, relate it to other tables, enforce field types, and build forms or reports on top of the data.
How to convert TSV to ACCDB
Microsoft Access APP
In Access, go to External Data > New Data Source > From File > Text File, select your .tsv, choose Delimited with Tab as the separator, and follow the Import Wizard to create a new table in the current .accdb.
Microsoft Excel APP
Open the .tsv in Microsoft Excel and save it as XLSX, then import that spreadsheet into Microsoft Access via External Data > Excel as an alternative two-step route.

- No free tool writes ACCDB natively; LibreOffice Base can import TSV data but saves as the older
.mdbformat, not.accdb. - Numeric and date fields are imported as text by default; set the correct data type in the Import Wizard field options to avoid later conversion issues.
- If the TSV is updated regularly, use Access's linked-table option to keep the connection live and convert to a local table only when the data is final.
