Upload multiple files to Airtable attachment fields and match each file to the correct record with miniExtensions Bulk Upload Attachments. A unique identifier in your table is matched against the filename, so you can attach a collection of files without opening records one by one.
What you can do
- Upload a collection of files and match filenames to record identifiers.
- Choose exact or partial matching.
- Skip or replace existing files with the same name.
- Review unmatched files and choose whether to create records for them.
Matching and existing files
Matching uses the filename without its extension and is case-insensitive. With Exact Match, CLIENT-104.pdf can match a record whose identifier is CLIENT-104. With Partial Match, CLIENT-104_contract.pdf and CLIENT-104_photo.jpg can both match that record. Use distinct identifiers so filenames do not accidentally match more than one record.
Skip leaves an existing same-named attachment in place. Overwrite replaces that file with the new upload while retaining the record’s other attachments. Files with different names are added alongside them. This makes repeated uploads useful without requiring the entire attachment field to be replaced.
Unmatched files are available for review. Creating records for them is a separate action, and the new record receives the filename-based identifier and attachment. Use a writable text or number-style identifier field, especially when you want to create records from unmatched files. Test Mode lets you try one file first.
Examples of useful workflows
Attach customer documents
Use a customer reference in each filename to match contracts or other documents to the appropriate customer record.
Upload several images per product
Use a unique product identifier in every image filename and Partial Match to place related images in the same record. Check that product identifiers do not overlap.
Replace revised files
Use Overwrite when a revised document has exactly the same filename as the stored attachment. A different filename adds another attachment instead of replacing the old one.
How to get started
Choose your table, a writable identifier field, and the destination attachment field. Select the matching and replacement options, then upload a sample before the full collection.
Good to know
Use distinct writable identifiers to avoid ambiguous matches. Overwrite replaces the same-named file while preserving other attachments.
