Merge Multiple Parquet Exports into One Word File
Combine monthly or per-channel Parquet exports into consolidated files with auto-aligned columns and deduplication.
Three Exports In, One File Out
Upload your first file, then add the rest in Merge Data. Columns align by header name, so reordered or renamed columns never scramble your rows.

Upload July's file. Its columns establish the file headers, and its rows become the first entries.
August lists Total before Qty. Merge Data matches by column name, not index, placing each value under the correct header.
September labels the column Order Number. Map Order Number to Order ID to merge rows into the existing column.
Only September includes Discount Code. It appends as a new column, leaving July and August cells blank.
Order #1046 appears in both August and September. Remove Duplicates on Order ID keeps the original entry and drops the repeat.
Sort Columns on Order Date puts the quarter in chronological order. Download one Word file with all 8 orders.
Align Renamed Columns Without Editing Source Files
Merge Data consolidates every unique column across files into one mapping table. Map renamed fields, uncheck redundant columns, and apply.
Select which source column maps to each unified field, or leave blank. Uncheck a column to omit it from the export.
| Keep | Column | orders-2026-07.parquet | orders-2026-08.parquet | orders-2026-09.parquet |

| Customer Email | ||||
| Product | ||||
| Qty | ||||
| Total | ||||

Matching column names align automatically across files, regardless of their position in each upload.
September has no Order ID column, leaving its mapping blank and ready for assignment.
Choose Order Number from the dropdown to map September orders directly into Order ID.
Uncheck Order Number so it is not appended as a duplicate column. Discount Code remains checked for new data.
Apply mappings to merge 9 rows into 8 columns, ready for deduplication and export as Word.

Frequently asked questions
How many exports can I merge at once?
Upload your first file, then add additional files in Merge Data. A free account is required to store uploaded files as datasets according to your plan limits.
What if columns appear in different orders across files?
Columns match automatically by header name rather than position, ensuring fields like Total and Qty always align correctly.
What if a file uses a different column name?
Unmatched headers display as blank. In Match Columns, map the renamed column (such as Order Number to Order ID) and uncheck any leftover fields so they do not append extra columns.
How do I eliminate duplicate records?
Run Remove Duplicate Records on your unique identifier column (like Order ID). The first occurrence is preserved and later duplicates are removed.
Can I track which file each row originated from?
Rows maintain the sequence of your uploads. To arrange combined records chronologically across all files, use Sort Columns on a date or timestamp column.
